Question #10 (9 points) USA Today reported that the population mean life span of people who live in Hawaii is 77 years. A random sample of 20 obituary notices gave a sample mean life span of x= 71.4 years and a sample standard deviation s = 20.65 years. Assuming that the life span of people in Hawaii is normally distributed, does this indicate that the population mean life span is less than 77 years? Use a 5% level of significance. a.) What is a? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two- tailed test? a = Ho: H = H1: / Select an answer The test is a Select an answer v] test b.) Identify the Sampling Distribution you will use. What is the value of the test statistic? The best sampling distribution to use is the Select an answer v | distribution. The test statistic (z or t value) is = c.) Find or estimate the P-value for the test. The p-value is = Select an answer d.) Conclude the test. Based on this we will Select an answer v| the null hypothesis
