Question 16-19 are related to the following To test the hypothesis that the average daily visit to a state park during the season is less than 200, a random sample of days yielded the following data (number of vehicles). 181 218 185 191 189 215 184 177 203 195 191 189 214 184 203 197 184 209 189 213 197 190 203 195 Test the hypothesis at a 5% level of significance. 16 The sample mean is, a 189.86 191.77 193.71 195.67 17 The variance of the mean is, a 5.702 6.335 131.139 136.841 18 The test statistic for the hypothesis test is, |TS| = a 1.556 1.638 1.724 1.815 19 Determine the critical value. CV = 1.531 Do not reject the null hypothesis. Do not conclude the mean is below 200. nop CV = 1.620 Do not reject the null hypothesis. Do not conclude the mean is below 200. CV = 1.714 Reject the null hypothesis. Conclude the mean is less than 200. CV = 1.814 Reject the null hypothesis. Conclude the mean is less than 200
