7. Below are data showing the results of six subjects on a memory test. The three scores per subject are theirscores on three trials (a, b, and c) of a memory task. Are the subjects getting better each trial? Test the linear effect of trial for the data.

a. Compute L for each subject using the contrast weights -1, 0, and 1. That is,

compute (-1)(a) + (0)(b) + (1)(c) for each subject.

b. Compute a one-sample t-test on this column (with the L values for each

subject) you created.

This is the table I couldnt make it in another format
