Question: 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

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	Time y
48	7
74	4
52	8
79	3.5
83	2
56	6
85	2.3
63	5
88	2.1
74	4.5
90	1.9
92	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.

Test the significance of the correlation coefficient and the regression equation at a level of significance of .01.

Select one:

a. The p-value equals .05. The correlation coefficient is not significant.

b. The p-value is equal to .0000000869049. The correlation coefficient is significant.

c. The p-value is equal to .006519. The correlation coefficient is significant.

d. The p-value equals .00000000425. The correlation coefficient is not significant.
