1) A researcher develops a social anxiety inventory for which the mean score in the general population is expected to be 50, with higher scores indicating greater social anxiety. The researcher hypothesizes that computer programmers are more socially anxious than the general population. To test this hypothesis, the social anxiety inventory is administered to a randomly- selected sample of 40 computer programmers, for whom the mean score is 60 with a standard deviation of 15. Determine whether the sample of computer programmers experience more social anxiety than the general population (one-tailed test with alpha = .01). 14 marks
