A)

You are performing a left-tailed matched-pairs test with 17 pairs of data. You believe the population of difference scores is normally distributed, but you do not know the standard deviation. If o = .025, find the critical value, to two decimal places.A survey of 30 people was conducted to compare their selfreported height to their actual height. The difference between reported height and actual height was calculated. You're testing the claim that the mean difference is greater than 0.9. From the sample. the mean difference was 1.1. with a standard deviation of 0.48. Calculate the test statistic. rounded to two decimal places You wish to test the following claim (HE) at a significance level of o: = 0.01. For the context of this problem, pg 2 \"2 m where the rst data set representsa pretest and the second data set represents a posttest.
