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=

Which of the following is a requirement that must be true in order to run a t-test over a z-test? a) the standard deviations for both populations must be known b) the standard deviations should come from each sample c) if the sample sizes are less than 30, the populations need to be approximately normal d) the populations must be approximately 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
