The relationship between "strength" and "fineness" of cotton fibers was the subject of a study that produced the following data. (Give your answers correct to two decimal places.)
x, Strength | 75 | 78 | 74 | 69 | 80 | 82 | 80 | 86 | 70 | 88 |
y, Fineness | 3.8 | 4 | 4.5 | 3.7 | 4.3 | 3.8 | 3.8 | 4.7 | 4.8 | 3.7 |
(a) Find the 98% confidence interval for the mean measurement of
fineness for fibers with a strength of 76.
