Bob Feller, an Iowa farmer, has recorded the daily high temperatures during the same five- day stretch in May over the past five years. Bob is interested in whether this data suggests that the daily high temperature obeys a normal distribution. Use a = 0.01 and conduct a goodness of fit test using 5 classes to see whether the following sample appears to have been selected from a normal probability distribution. (Note: x = 68.2 and s = 18.) 53 53 84 92 56 53 93 53 50 67 93 88 63 85 48 54 55 96 56 77 90 60 57 86 43 Ho: The population has a normal probability distribution. Ha: The population does not have a normal probability distribution. Find the value of the test statistic. Find the p-value. (Round your answer to four decimal places.)
