• A scholar is interested in whether the average IQ of the students in her class is significantly different from the average IQ in the population. IQ tests were administered to 25 students and the mean IQ in the class was 110 with a standard deviation of 10. The average IQ of the population was 100. Test the null hypothesis at the .05 level that the average IQ in of the students in her class is higher than the average IQ of the population. In so doing, identify (1) the research and null hypotheses, (2) the critical value needed to reject the null, (3) the decision you made upon analyzing the data, and (4) the conclusion you have drawn based on the decision you have made
