A hospital has a main campus and three satellite locations. Management wants to reduce waiting time for ER cases. A random sample of 11 ER cases at each location was selected, and the waiting time was measured.
Excel.) Complete parts (a) through (d) to determine if there is statistical evidence of a difference in the mean waiting times betweeen the four locations.
a. State the two hypotheses. Choose the correct answer below.
O B. Ho: H1 = H2 = ••• = H4
H;: 41 H2# • • • # µ4
O A. Ho: H1 =H2 = ••• = H4
H;: Not all H are equal
(where j= 1,2,.4)
OC. Họ: H1 = H2 = • •• = H1
H;: 41 # H2# • •• #H11
D. Ho: H1 = H2= • •• - H11
H;: Not all H; are equal
(where j= 1,2,.,11)
b. At the 0.05 level of significance, state the test statistic. (Round to two decimal places to the right of the decimal point as needed.)
O A. FSTAT = 0.005 , from the first row of the ANOVA table
O B. FSTAT = 4.91 , from the first row of the ANOVA table
O C. FSTAT = 2.05 , from the first row of the ANOVA table
O D. FSTAT = 2.84 , from the first row of the ANOVA table
c. For a level of significance of 0.05, state the p-value. (Round to three decimal places to the right of the decimal point as needed.)
O A. p-value = 0.011 , from the first row of the ANOVA table
O B. p-value = 0.120 , from the first row of the ANOVA table
OC. p-value = 2.839 , from the first row of the ANOVA table
O D. p-value = 0.005 , from the first row of the ANOVA table
