A representative of a car manufacturer in the United States made the following claim in a news report. "Ten years ago, only 53 p
Harman [31]

According to the p-value, the correct option regarding the decision of the test hypothesis is:

v. No, because 0.283 > 0.05.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, we test if the proportion is still of 0.53, that is:

H_0: p = 0.53

At the alternative hypothesis, we test if it has increased, that is:

H_1: p > 0.53.

<h3>What is the decision according to the p-value?</h3>

  • If p-value > significance level, we do not reject the null hypothesis.
  • If p-value < significance level, we reject the null hypothesis.

In this problem, the p-value is of 0.283 > 0.05, hence there is not sufficient evidence to conclude, at the significance level of a = 0.05, that the proportion of all car owners in the United States who own American-made cars has increased from what it was ten years ago, which means that option V is correct.

Veseljchak [2.6K]
The volume of rectangular prism is the product of its length, width and height. 
So the volume V of prism with length 1 \frac{1}{4} yards, width 2 \frac{1}{2} yards and height of 4 yards will be:

V=1 \frac{1}{4} * 2 \frac{1}{2} *4 \\  \\ &#10;V=  \frac{5}{4}* \frac{5}{2}*4 \\  \\ &#10;V= \frac{25}{2} \\  \\ &#10;V=12 \frac{1}{2}

Thus the volume of prism as a mixed number in simplest form will be 12 \frac{1}{2} cubic yards
