historically, about 57% of the population of a certain country believed that the planets temperature was rising (global warming). a march 2010 poll wanted to determine whether this proportion had changed. the poll interviewed 1065 adults in the population, and 593 said they believed that global warming was real. (assume these 1065 adults represented a simple random sample.) complete parts a through c below. p - value = 0.390 (round to three decimal places as needed.) do you reject or not reject the null hypothesis? reject h0 do not reject h0. c. choose the correct interpretation. a. in 2010, the percentage of the population who believe global warming is real has not changed from the historical level of 57%. b. in 2010, the percentage of the population who believe global warming is real is significantly different from 57%.

Answer

Explanation:

Step1: Recall hypothesis - testing decision rule

If the p - value is greater than the significance level (commonly $\alpha = 0.05$), we do not reject the null hypothesis. Here, the p - value is 0.390 which is greater than 0.05.

Step2: Interpret the non - rejection of null hypothesis

The null hypothesis $H_0$ usually assumes no change from the historical proportion. Since we do not reject $H_0$, it means there is not enough evidence to suggest a change from the historical proportion.

Answer:

A. In 2010, the percentage of the population who believe global warming is real has not changed from the historical level of 57%.
