*1. A key factor in the world’s economic condition is the population growth of regions. The accompanying data table contains data for all of the world’s 232 regions. 1 Click the icon to view the data table. a. From this population, suppose a systematic random sample of every fifth region is selected starting with the fifth region on the list. From this sample, test the null hypothesis that the mean population growth between the years 1990 and 2000 is equal to 1.4%. Test using a = 0.10. b. Now compute the average population growth rate for all 232 regions in the data table. After examining the result of the hypothesis test in part a, what type of statistical error, if any, was committed? Explain your answer. a. Note that for the purposes of this exercise, the t-test will be used. State the appropriate null and alternative hypotheses. Choose the correct answer below. A. Ho: 21.4 HA: H <1.4 OD. Ho: H 1.4 HA: H>1.4 Calculate the test statistic of the sample data. t= (Round to two decimal places as needed.) Find the p-value of the sample data. p-value= (Round to three decimal places as needed.) State the conclusion. Choose the correct answer below. B. Ho: >1.4 HA: H 1.4 O E. Ho: #1.4 HA: H=1.4 OA. Do not reject the null hypothesis. There is not sufficient evidence at significance level = 0.10 to indicate that the mean population OB. Reject the null hypothesis. There is sufficient evidence at significance level = 0.10 to indicate that the mean population growth rat OC. Reject the null hypothesis. There is not sufficient evidence at significance level = 0.10 to indicate that the mean population growt! O D. Do not reject the null hypothesis. There is sufficient evidence at significance level = 0.10 to indicate that the mean population gro b. Find the population mean for the population growth rate. = (Round to three decimal places as needed.) What type of statistical error, if any, was committed? 1: Population growth rate OA. The systematic sample should start with the third region in the list instead of the fifth region. OB. The sample in part a is not a random sample. OC. Only the population data should be used for the hypothesis test. OD. No statistical error was made.
