B. Find and interpret a 90% confidence interval for the difference between the mean reading speeds of all people using program 1 and all people using program 2. 1. State the type of test that is needed for the question2. State the Null and lternative hypothesis very clearly.3. Provide the test statistic4. Provide the p-value5. State your decision (either to reject the Null or not to reject the Null6. Write down the conclusion in the context of the problem.

2. The effectiveness of two speed reading programs is being compared. Ten pairs of people are randomly selected; each pair consists of people whose present reading speeds are essentially identical. From each pair, one person is randomly selected to take Program 1; the other person takes Program 2. After the speed reading programs are completed, the reading speeds, in words per minute, for the 10 pairs of people are found to be: Program 1 Program 2 a. At the 10% significance 1114 1032 level, can we conclude 979 1074 that there is a difference 910 959 in effectiveness of the two 1091 1091 speed reading programs? 996 1032 (Assume that the 996 1148 populations being 1125 1076 sampled are 1056 1094 approximately normally 1053 1096 distributed.)
