Compute the z-statistic you would use if you wanted to examine whether the mean age of marriage within a local cult is significantly different from the mean age of marriage in the general population. You also know that the mean age of marriage in the general population is 29.23, with a population standard deviation of 4.13. Compute z for the following data set from your cult sample: 13, 15, 16, 18, 51, 12, 65, 25 Now compute the appropriate t-test on the data from your cult sample, with the assumption that you only have population information regarding the mean of 29.23. Assuming a sample standard deviation of 19.97, what is your tobt? Using an alpha level of .05, what can you conclude about your cult sample now that you've computed tobt?
