A fast-food franchiser is considering building a restaurant at a certain location. Based on financialanalyses, a site is acceptable only if the number of pedestrians passing the location averages more than100 per hour. The number of pedestrians observed for each of 40 hours was recorded. Data is availableat fast-food.txtAssuming that the population standard deviation is known to be 16, can we conclude at the 5%significance level that the site is acceptable?The appropriate null and alternative hypotheses, Ho and Ha, for μ areO Hoμ 100 vs Ha : μ ‡ 100=Ο Ηo : μ100 vs H₂ μ> 100O Ho : | = 100 vs Ha : p < 100=

To estimate u, the mean salary of full professors at American colleges and universities, you obtain the salaries of a random sample of 400 full professors. The sample mean is x = $73,220 and the sample standard deviation is s = $4400. Which of the following conditions is NOT required to construct a 90% confidence interval for u? Oa random 10n SN np 2 10 and n(1-p) 210 n2 30 or stated as normal
ou can use both the t statistic and the z statistic to test hypotheses about the mean of population. The test that uses the t statistic is typically referred to as a t test, while the test that uses z statistic is commonly called a z test. Which of the following statements are true of the t statistic? Check all that apply. The t statistic does not require any knowledge of the population standard deviation. The t statistic provides an excellent estimate of z, particularly with small sample sizes. The t statistic uses the same formula as the z statistic except that the t statistic uses the estimated standard error in the denominator. The formula for the t statistic is t = (M – μ) / σM

A sample mean of 22298, sample standard deviation of 14200, and sample size of 17, Ho μ=30000, H1: p+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. a. Test statistic: t = -2.24. P-value = 0.035; Do not reject the null hypothesis. O b. Test statistic: t = -2.24. P-value = 0.35; Do not reject the null hypothesis. c. Test statistic: t = -2.24. P-value = 0.35; Reject the null hypothesis. O d. Test statistic: t = -2.24. P-value = 0.035; Reject the null hypothesis.
