For Exercises 1 through 7, do a complete regression analysis by performing the following steps. a. Draw the scatter plot. b. Compute the value of the correlation coefficient. c. Test the significance of the correlation coefficient at a 0.01, using Table I. d. Determine the regression line equation. e. Plot the regression line on the scatter plot. f. Predict y for a specific value of x.Typing Speed and Word Processing A researcher desires to know whether the typing speed of a secretary (in words per minute) is related to the time (in hours) that it takes the secretary to learn to use a new word processing program. The data are shown. Speed x 48 74 52 79 83 56 85 63 88 74 90 92 Time y 7 4 8 3.5 2 6 2.3 5 2.1 4.5 1.9 1.5 If there is a significant relationship, predict the time it will take the average secretary who has a typing speed of 72 words per minute to learn the word processing program. (This information will be used for Exercises 9 and 11.)
