Infant Sleep Patterns

Explain your choice of answers for the above three situations

A study of the sleep patterns of 6-month-old infants in the United States reported a 95% confidence interval for the average amount of time infants sleep (out of every 24 hour period) to be (11.5 hours, 15.2 hours).

Suppose we want to test H0 :μ = 15 versus H1 :μ ≠ 15.

At the 5% level, we would:
♦ Fail to reject H0
♦ Reject H0
♦ Can't tell

At the 1% level, we would:
♦ Fail to reject H0
♦ Reject H0
♦ Can't tell

At the 10% level, we would:
♦ Fail to reject H0
♦ Reject H0
♦ Can't tell
