A certain IQ test is known to have a population mean of 100 and standard deviation of 15 in the general population. You want to test whether psychology majors have a different average IQ than the population as a whole. Assume the variance of IQ is the same for Psych majors as it is in the general population. Suppose that Psychology majors actually have an average IQ of 108. If you do a 2tailed test at o= .05 with a sample of 56 Psychology majors, you will be able to reject the null hypothesis if the mean IQ of your V sample is below [59'9\"] or above [ Select ] 96-08 _ 98.00 103.92 104.08 110.00 111.92 A certain IQ test is known to have a population mean of 100 and standard deviation of 15 in the general population.
