[Hypothesis Testing] We are given the following data: n = 40, xbar = 105.7, standard deviation = 16a) State the null and alternative hypotheses using H0, Ha, and mub) Calculate the test statistic using z = (xbar - mu) / (standard deviation / sqrt (n))c) Calculate the p-valued) Should the null hypothesis be rejected or not? 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=

Are there differences in airfare depending on which travel agency website you utilize? Suppose the following data were collected on travel agency websites on certain day. The following table contains the prices in U.S. dollars for a oneway ticket between the cities listed on the left for each of the three travel agency websites. Here the pairs of cities are the blocks and the treatments are the different websites. Ho: MA Flight From-To Atlanta to Seattle New York to Los Angeles Ha Cleveland to Orlando Dallas to Indianapolis = MB = MC H₂: MA MB MC # A ($) B 175.50 MC Website O Ho: MA MB MC # # Ha: MA = MB =нс B ($) 166.00 194.50 195.00 Use a = 0.05 to test for any significant differences in the mean price of a oneway airline ticket for the three travel agency websites.
