Answer:

C

Step-by-step explanation:

Express - 1 \frac{4}{5} as an improper fraction, that is

- \frac{9}{5} x = 9 ( multiply both sides by 5 )

- 9x = 45 ( divide both sides by - 9 )

x = - 5 → C

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.
