Question

The mean annual tuition and fees for a sample of 14 private colleges was 38,100 with a standard deviation of 6000 A dotplot shows that it is reasonable to assume that the population is approximately normal. You wish to test whether the mean tuition and fees for private colleges is different from 33,900. State a conclusion regarding H0. Use the level of significance a=0.01. There is not enough information to draw a conclusion. Reject H0. The mean annual tuition and fees appears to be different from $33,900. Do not reject H0. There is insufficient evidence to conclude that the mean annual tuition and fees is different from $33,900.
