Reference no: EM131008432

The manufacturer of a new sleeping pill suspects that it may increase the risk of sleepwalking, which could be dangerous. A test of the drug fails to reject the null hypothesis of increased sleepwalking when tested at alpha = .01.

a) If the test had been performed at alpha = .05, would the test have been more or less likely to reject the null hypothesis of no increase in sleepwalking?

b) Which alpha level do you think the company should use? Why?
