A researcher wishes to see if the total number of infections that occurred in three groups of randomly selected hospitals is the same. The data are shown in the table. Group A 557 315 920 178 Group B Group C 105 110 167 476 232 80 116 155 At a = 0.05, is there enough evidence to reject the claim that the number of infections in the three groups of hospitals is the same? a. Since the computed value of 5.346 is less than the tabulated value of 5.991, there is no enough evidence to reject the claim that there is no difference in the number of infections in the groups of hospitals. b. Since the computed value of 5.991 is greater than the tabulated value of 5.346, there is enough evidence to reject the claim that there is no difference in the number of infections in the groups of hospitals. c.

Question
A researcher wishes to see if the total number of infections that occurred in three groups of randomly selected hospitals is the
same. The data are shown in the table.
Group A
557
Group B
Group C
105
476
232
315
110
920
80
167
178
116
155
At a = 0.05, is there enough evidence to reject the claim that the number of infections in the three groups of hospitals is the
same?
a. Since the computed value of 5.346 is less than the tabulated value of 5.991, there is no enough evidence to reject the claim
that there is no difference in the number of infections in the groups of hospitals.
b. Since the computed value of 5.991 is greater than the tabulated value of 5.346, there is enough evidence to reject the claim
that there is no difference in the number of infections in the groups of hospitals.
c. Since the computed value of 5.346 is less than the tabulated value of 5.991, there is enough evidence to reject the claim
that there is no difference in the number of infections in the groups of hospitals.
d. Since the computed value of 5.991 is less than the tabulated value of 5.346, there is no enough evidence to reject the claim
that there is no difference in the number of infections in the groups of hospitals.
