In this problem, assume that the distribution of differences isapproximately normal. Note: For degrees of freedomd.f. not in the Student's t table, usethe closest d.f. that is smaller. Insome situations, this choice of d.f. may increasethe P-value by a small amount and therefore produce aslightly more \"conservative\" answer.
At five weather stations on Trail Ridge Road in Rocky MountainNational Park, the peak wind gusts (in miles per hour) for Januaryand April are recorded below.
| Weather Station | 1 | 2 | 3 | 4 | 5 |
| January | 135 | 122 | 128 | 64 | 78 |
| April | 108 | 115 | 102 | 88 | 61 |
What is the value of the sample test statistic? (Round youranswer to three decimal places.)
