An analyst collected data from 25 randomly selected transactions and found the purchase amounts (in $). The mean is $29.01 and the standard deviation is $12.48. The analyst wants to know if the mean purchase amount of all transactions 34.97 47.97 45.78 35.01 34.59 is at least $22. Use the given information to complete parts a through e. 22.27 11.25 15.13 15.65 43.95 7.64 40.91 25.06 23.76 30.81 44.44 18.99 13.88 20.19 44.25 13.93 39.33 41.17 30.89 23.37 a) What is the null hypothesis? Ho: V V s (Type an integer or a decimal.) b) Is the alternative one- or two-sided? The alternative hypothesis is c) What is the value of the test statistic? The test statistic is (Round to two decimal places as needed.) d) What is the P-value of the test statistic? P-value = (Round to four decimal places as needed.) e) What do you conclude at a = 0.05? The P-value is a, So the null hypothesis. There is evidence to conclude that the mean purchase amount of all transactions is greater than $22
