Answer to Question #187814 in Statistics and Probability for tahreem anwar
Question #187814
A random sample of 150 workers with children in day care shows a mean day care cost Rs. 3200 and a standard deviation of Rs. 750. Verify the department’s claim that the mean does not exceeds Rs. 3000 at 5% level of significance with this information.
Expert's answer
z = (3200-3000)/(750/"\\sqrt{150}" ) = 3.27
P(z>3.27)=0.000538.
Mean does exceed Rs. 3000.
The result is significant at 5% level of significance.
