We have learned how to conduct tests about the population proportion. (yes)

We have learned how to conduct tests about the population standard deviation. (no)

For some tests, we start off assuming Ha is true. (no)

We have studied the Rejection Region approach and the p-value approach. (yes)

Solutions

Expert Solution

Solution:-

1) In many cases, we conclude that both Ho and Ha must be true. (no)

Both the hypothesis can never be true. if H0 is true then HA would be false.

2) We have learned how to conduct tests about the population mean. (yes)

3) We have learned how to conduct tests about the population proportion. (yes)

4) We have learned how to conduct tests about the population standard deviation. (no)

5) For some tests, we start off assuming Ha is true. (no)

We never assume that the statement Ha is true while starting the hypothesis test, we always start with the assumption that H0 hypothesis is true.

6) We have studied the Rejection Region approach and the p-value approach. (yes)
