Question

For dependent samples, we assume the population distribution of the paired difference has a mean of

a. 0

b. 4

c. 3

d. 2

Answer 1

              The paired sample t-test hypotheses are formally defined below:

• The null hypothesis (H0) assumes that the true mean difference (μd) is equal to zero.
• The two-tailed alternative hypothesis (H1) assumes that μd is not equal to zero.
• The upper-tailed alternative hypothesis (H1) assumes that μd is greater than zero.
• The lower-tailed alternative hypothesis (H1) assumes that μd is less than zero

  Option [a] =0 The population distribution of the paired difference has a mean of Zero (0)
