Consider the following competing hypotheses: (You may find it useful to reference the appropriate table: z table or t table)

Hypotheses: H0: μD ≤ 2; HA: μD > 2

Sample results: d−d− = 5.6, sD = 6.2, n = 10

The following results are obtained using matched samples from two normally distributed populations:

a. Calculate the value of the test statistic, assuming that the sample difference is normally distributed. (Round all intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

Answer #1

Test statistic,
t = (dbar - 2)/(s(d)/sqrt(n))
t = (5.6 - 2)/(6.2/sqrt(10))
t = 1.836

Ans: 1.836
