2	62	95	45
3	75	98	30
4	48	87	58
5	65	90	57
Mean	60	90	50

Test whether there is a difference in the mileage of the three brands using α by 10%.

A student researcher conducted a new study (N=10) on intelligence using a newly created measure, the IQ-5000 and wanted to compare his results to a similar study that used a different, but the commonly used measure, the WAIS. Both studies indicated that intelligence is normally distributed, but the student wanted to convert scores into z scores for comparison. After converting the scores in his study to z scores, he got the following: -4.7, 4.8, 0.9, -6.5, 3.1, -2.8, -5.3, 7.2,...
