The Answer of We want to test to see if the mean time to complete a task is more than 60 minutes. A random sample of
100 people are selected and $$\text { alpha } = .05$$ If the population standard deviation is 30 minutes, determine the
power of the test if the population mean is 97 minutes.

We Want to Test to See If the Mean Time alpha =.05\text { alpha } = .05 alpha =.05

We Want to Test to See If the Mean Time $\text { alpha } = .05$
