Question:

The calculated value of the test statistic is actually the number of standard errors that the sample mean differs from the hypothesized value of µ in the null hypothesis. Suppose that the null hypothesis is Ho: µ = 4.5 , σ is known to be 1.0, and a sample of size 100 results in  = 4.8 .
a. How many standard errors is above 4.5?
b. If the alternative hypothesis is Ha: µ = 4.5 and , would you reject Ho?
