Question 187151
At the .05 level of significance, can we conclude that the mean number of interviews conducted by the agents is more than 53 per week? Why? Explain your decision on the null hypothesis.


Hypothesis Test: Mean vs. Hypothesized Value

53.000 hypothesized value 
56.882 mean Data 
3.199 std. dev. 
0.776 std. error 
17 n 
16 df 

5.00 t 
.0001 p-value (one-tailed, upper) 

55.237 confidence interval 95.% lower 
58.527 confidence interval 95.% upper 
1.645 half-width 
-----------------------------------------
Ho: u(daily) = 53
Ha: u(daily) > 53
---
Conclusion: since the p-value is less than 5%, reject Ho.
The test provided evidence that the agent's daily average is greater than 53.
