A sample mean of 22298, sample standard deviation of 14200, and sample size of 17, Ho μ=30000, H1: μ+30000, a=0.05 are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the P-value approach. Also, assess the strength of the evidence against the null hypothesis. O a. Test statistic: t = -2.24. P-value = 0.35; Reject the null hypothesis. O b. Test statistic: t = -2.24. P-value = 0.35; Do not reject the null hypothesis. O c. Test statistic: t = -2.24. P-value = 0.035; Reject the null hypothesis. O d. Test statistic: t = -2.24. P-value = 0.035; Do not reject the null hypothesis.

Question 8 Not yet answered P Flag question One of the biggest issues facing e-retailers is the ability to turn browsers into buyers. This is measured by the conversion rate, the percentage of browsers who buy something in their visit to a site. The conversion rate for a company's website was 9.1%. The website at the company was redesigned in an attempt to increase its conversion rates. A samples of 200 browsers at the redesigned site was selected. Suppose that 29 browsers made a purchase. The company officials would like to know if the conversion rate remains the same after the redesigned website. Which of the following is correct? O a. H0: p = 0.091 versus H1: p = 0.091, significance O b. H0: p ≤ 0.091 versus H1: p > 0.091, significance O c. H0: p ≤ 0.091 versus Hl: p > 0.091, O d. H0: p = 0.091 versus H1: p = 0.091, do not reject HO do not reject HO reject HO reject HO at 0.1 level of at 0.05 level of at 0.1 level of significance at 0.05 level of significance
