The sample data below are the typing speeds (in words per minute) and reading speeds (in words per minute) of nine randomly selected secretaries.
Typing Speed, x | Reading Speed, y |
63 | 370 |
56 | 420 |
52 | 528 |
63 | 348 |
70 | 645 |
58 | 454 |
44 | 413 |
79 | 510 |
62 | 500 |
Determine whether the data provide sufficient evidence to conclude that typing speed and reading speed are linearly correlated. Test at the 10% significance level.
Group of answer choices
Test statistic: t = 0.35132 Do not reject H0. At the 10% significance level, the data do not provide sufficient evidence to conclude that typing speed and reading speed are linearly correlated.
Test statistic: t = 0.99844 Reject H0. At the 10% significance level, the data provide sufficient evidence to conclude that typing speed and reading speed are linearly correlated.
