Explanation:
A teacher tells her students that a large jar of marbles contains 55% red marbles. students randomly select a sample of 40 marbles and determined the proportion of red marbles. one sample a student selected contained 16 red marbles. assuming the teacher’s claim is true, 100 simulated proportions are displayed in the dotplot. using the dotplot and sample proportion, is there convincing evidence that the teacher’s claim is false? yes, because a proportion of 0.40 or more occurred 98 out of 100 times, the sample proportion of red marbles is statistically significant and there is convincing evidence that the teacher’s claim is false. yes, because a proportion of 0.40 or less occurred only 2 out of 100 times, the sample proportion of red marbles is statistically significant and there is convincing evidence that the teacher’s claim is false. no, because a proportion of 0.40 or more occurred 98 out of 100 times, the sample proportion of red marbles is not statistically significant and there is not convincing evidence that the teacher’s claim is false. no, because a proportion of 0.40 or less occurred 2 out of 100 times, the sample proportion of red marbles is not statistically significant and there is not convincing evidence that the teacher’s claim is false.
There is convincing evidence that the teacher's claim is false because:
"a proportion of 0.45 or more occurred 87 out of 100 times" (Option A).
Why is the Teacher's Claim False?
The teacher's claim is false because a percentage of 0.45 or more occurred 87 out of 100 times.
What this says is that the sample of red marbles is statistically significant.
Therefore, the teacher's claim that the large jar of marbles contains 55% red marble is false.

A quality control engineer is testing the battery life of a new smartphone. the company is advertising that the battery lasts 242424 hours on a full charge, but the engineer suspects that the battery life is actually less than that. they take a random sample of 303030 of these phones to test h_0: \mu=24h 0 :μ=24h, start subscript, 0, end subscript, colon, mu, equals, 24 hours versus h_\text{a}: \mu < 24h a :μ<24h, start subscript, start text, a, end text, end subscript, colon, mu, is less than, 24 hours, where \muμmu is the mean battery life of these phones. the sample data had a mean of 212121 hours and a standard deviation of 161616 hours. these results produced a test statistic of t\approx-1.03t≈−1.03t, approximately equals, minus, 1, point, 03 and a p-value of approximately 0.1560.1560, point, 156. assuming the conditions for inference were met, what is an appropriate conclusion at the \alpha=0.10α=0.10alpha, equals, 0, point, 10 significance level?
The appropriate conclusion of the hypotheses is that; there is insufficient evidence to support the claim that the mean battery life not up to 24 hours.
What is the Conclusion of the Hypothesis?
We are given;
Null Hypothesis; H₀: μ = 24
Alternative Hypothesis; Hₐ: μ < 24
We are aslo given that;
Significance level; α = 0.10
test statistic; t = 1.03
p-value = 0.156
Now, we see that our p-value is greater than the significance value and as such since the alternative hypothesis is the claim we will fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean battery life not up to 24 hours.

A rectangular tank that is with a square base and open top is to be constructed of sheet steel of a given thickness. find the dimensions of the tank with minimum weight.
The dimensions of the tank with minimum weight are; 26 ft by 26 ft by 13 ft.
How to minimize functions?For minimum weight, it means that the surface area must be minimum.
Let the height be h and the lengths be x
Thus, the volume is;
x²h = 8788
Thus;
h = 8788/x²
Surface Area is;
A = x² + 4xh
A = x² + 35142/x
dA/dx = 2x - 35152/x²
When dA/dx = 0, we have;
2x - 35152/x² = 0
2x =35152/x²
Thus;
2x³ = 35152
x³ = 17576
x = 26 ft
Thus;
h = 8788/x²
h = 8788/26²
h = 13 ft
Thus, the dimensions are 26 ft by 26 ft by 13 ft.

The correct statement is these two stocks must have the same dividend yield.
What is the dividend yield of the stock?Dividend yield of a stock is the dividend per share divided by the total market price of the stock.
Dividend yield = dividend per share / market price
Dividend per share = market value x (required return - expected growth)
Dividend per share for Stock X = $25 x (10% - 7%) = $0.75

A designer of soup cans wants to redesign the cans by enlarging the area of the base to three times the original size. The new can should hold the same amount of soup. How should the designer change the height of the can?
The designer should change the height of the can and maintain the same volume by doubling the area of the base of the can.
How to change the height of the canArea of a cylinder, V= πr²h
Where:
r= base radiush= height.Area of the base, A= πr²
So,
volume of the cylinder;
V= A×h
For instance,
if volume of a cylinder is 50cm³ and area of the base is 10cm²V= A*h
50 = 10 × h
50 = 10h
h = 50/10
h = 5cm
If the area of the base is doubled at a constant volume, that is A = 20cm², V = 50cm²V= A×h
50 = 20 × h
50 = 20h
h = 50/20

Saul paid off a loan with a simple interest rate of 4.7% in 9 months. what was the apr?
The annual percentage rate (APR) for Saul loan who paid off a loan with a simple interest rate of 4.7% in 9 months is 6.3%.
What is equivalent ratio?Equivalent ratio is the ratio which is same in the value as the original ratio but the numerator and denominator is different for both the ratios.
Saul paid off a loan with a simple interest rate of 4.7% in 9 months. Here, the rate of interest is 4.7%. The time period is 9 months. Thus, the ratio for rate to month is,
[tex]r=\dfrac{4.7}{9}[/tex]
Let the annual percentage rate (APR) is x%. Thus, the rate in 12 months is,
[tex]\text{12 months - x\%}[/tex]
[tex]r=\dfrac{x}{12}[/tex]
Comparing both the ratios,
[tex]\dfrac{x}{12}=\dfrac{4.7}{9}\\x=\dfrac{4.7}{9}\times 12\\x\approx 6.3\%[/tex]
Hence, the annual percentage rate (APR) for Saul loan who paid off a loan with a simple interest rate of 4.7% in 9 months is 6.3%.

A relation that assigns to each element x from a set of inputs or ________ exactly one element in a
The complete sentence is:
"A relation that assigns to each element x from a set of inputs or domain exactly one element in a..."
How to complete the sentence?
First, let's describe what a mathematical relation is.
A relation between two variables maps the element from the set of inputs, also called the domain, into the set of outputs, also called the range.
So we have something like:
y = h(x)
Where the relation h() is mapping the element x into the element y.
Now, the sentence that we need to complete is:
"A relation that assigns to each element x from a set of inputs or ________ exactly one element in a..."
So we need a synonym for the set of inputs, which we already know that is also called the domain, so the complete sentence would be:
