Consider the following competing hypotheses: (You may find it useful to reference the appropriate table: z table or t table)
Hypotheses: H0: μD ≤ 5; HA: μD > 5
Sample results: d− = 9.5, sD = 6.2, n = 13
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. (Negative value should be indicated by a minus sign. Round final answer to 3 decimal places.)
b. Find the p-value.
multiple choice 1
0.01 Picture p-value < 0.025
p-value < 0.01
p-value Picture 0.10
0.05 Picture p-value < 0.10
0.025 Picture p-value < 0.05
c. Use the 5% significance level to make a conclusion.
