# Question

Use the data given and the eight-step process to test the following hypotheses.

H0: µ1 - µ2 = 0 ....... Ha: µ1 - µ2 < 0

Sample 1 ... Sample 2

n1 = 8 ...... n2 = 11

x̄1 = 24.56 ... x̄2 = 26.42

s21 = 12.4 .... s22 = 15.8

Use a 1% level of significance, and assume that x is normally distributed.

H0: µ1 - µ2 = 0 ....... Ha: µ1 - µ2 < 0

Sample 1 ... Sample 2

n1 = 8 ...... n2 = 11

x̄1 = 24.56 ... x̄2 = 26.42

s21 = 12.4 .... s22 = 15.8

Use a 1% level of significance, and assume that x is normally distributed.
