a HealthPro has a significantly higher mean occupancy rate b

a. HealthPro has a significantly higher mean occupancy rate.

b. There appears to be no difference in the mean occupancy rates.

c. There is a significant difference in the mean occupancy rates.

Solution

P-value approach:

From the given output, test statistics is t=-1.3923. Since test is two tailed so p-value of the test from the output is 0.1791. Since p-value of the test is greater than 0.05 (level of significance) so we fail to reject the null hypothesis. Therefore \"There appears to be no difference in the mean occupancy rates.\" is correct.

Critical value approach:

For two tailed test, from the output, the critical value of the test is -2.086 and 2.086. Since test statistics t=-1.3923 lie between the critical values so we fail to reject the null hypothesis. Therefore \"There appears to be no difference in the mean occupancy rates.\" is correct.

That is option (b) is correct.
