Question

A paired difference experiment produced the data given below. Complete parts a through e below nd = 16-1 = 148 x2 = 152 xd =-4 s -25 a. Determine the values of t for which the null hypothesis μι-μ2-0 would be rejected in favor of the alternative hypothesis μι-μ·0. Use α-0.05. (Round to two decimal places as needed.) XA. The rejection region ist< ort» O B. The rejection region is t> ° C. The rejection region is <t< D. The rejection region ist -1.75 b. Conduct the paired difference test described in part a. Determine the test statistic. t=11 1 (Round to two decimal places as needed.)

Answer 1

b.

t =

sa/m

t = -4/(25/16)^(1/2)

t = -3.5
