A poll found that about 44% of residents of Country A believed that the Earth's temperature is rising (or that global warming is fact). In the same month, a survey of 1002 randomly chosen adults from a sufficiently large country, Country B, was taken, of whom 467 believed that global warming is fact. Complete parts a through d below. E) a. What percentage of the Country B sample believed global warming was fact? Is it more or less than the proportion of residents of Country A, or 44%? Select the correct choice below and ll in the answer box to complete your choice. (Round to one decimal place as needed.) The percentage is %, which is less than the proportion of residents of Country A. v The percentage is 46.6 %, which is more than the proportion of residents of Country A. b. Test the hypothesis that the proportion of residents of Country B who believe global warming is fact is different from the proportion of residents of CountryAwho believe global warming is fact. Use a significance level of 0.05. Determine the null and alternative hypotheses. Let p be the proportion of Country B adults who believe that global warming is fact. Ho: p = 0.44 HA: p # 0.44 (Type integers or decimals. Do not round.) Determine the test statistic. 1.66' (Round to two decimal places as needed.) Determine the p-value. 0.096V (Round to three decimal places as needed.) What is the proper conclusion? Do not reject H0 because the p-value is greater than the signicance level
