Please answer the following: (I just need 3, 4, and 5)

1. The following is a general statement of a decision rule: If, when the null hypothesis is true, the probability of obtaining a value of the test statistic as as of more than that actually obtained is less than or equal to, the null hypothesis 1S Otherwise, the null hypothesis is 2. The probability of obtaining a value of the test statistic as extreme as or more extreme than that actually obtained, given that the tested null hypothesis is true, is called for the test 50: Ha: 50: -0.05. A simple random sample of size 64 is drawn from a X= 45, s-256. The computed value of the test , which is compared for significance with a value from the 3. Given : Ho. non-normally distributed population. statstc 1S distribution

Solution

3) Test statistic = x bar/std error

x bar = 45

std error = rt of 256 =16

Test statistic = 45/16

= 2.8125

critical z value = -1.645

4) Ha: mu >= mu0

5) Ha: mu <=mu0
