Assume the population is normally dstrituted and use a t-distbution to construct a 99% car tidence interval for the population mean what is the ma n of error of p? Interpret the results. ork The corfidence interval for the population mean u is (29. 38) Round to one decimal place as needed The margin of error of is 45 pts. (Round to one decimal place as noeded ) Interpret the results e taken approximately 99% of them wil have commute tmes bati oen the bounts of the cantidence interval lfa large sample of people B Sub O A with 99% com idence it can be said that the population mean commute tine is between the bounds of the confidence interval ° C. WWn 95% confidence, it can be said Ihal the commute time is between the bounds of the confidence interval inc D.

Explanation / Answer
Here
Mu lies between confidance intervals.
Vs
Mu not lies between confidance intervals.
Here, mu lies between confidance intervals so accept Ho.
Therefore option D is Right.
