Question
The data in the accompanying table gives the food segment (burger, chicken, pizza, or sandwich) and average sales per unit ($ thousands) for each of 28 quick-service brands. Complete (a) through (d) below.
Click here to view the data table,
a. At the 0.05 level of significance, is there evidence of a difference in the mean U.S. average sales per unit ($ thousands) among the food segments? Determine the hypotheses. Choose the correct answer below.
O A. Ho: H1= H2 = ••• = H4
H1: Not all Hj are equal
(where j= 1,2,..,4)
O B. Ho: H1= H2 = ••: = H28
H1: Not all H are equal
(where j= 1,2,.,28)
O C. Ho: H1= H2 = • • • = H4
H1: µ1 H2 ••• +4
O D. Ho: H1 = µ2 = • • • = H28
H1: H1 H2# ••• µ28
b. Find the test statistic.
ESTAT = (Round to two decimal places as needed.)
c. Determine the critical value.
Fa = (Round to two decimal places as needed.)
d. Reach a decision.
Hn. There is
V evidence of a difference in the mean U.S. average sales per unit among the food segments.
