Solution 6BSC

Critical values

As the test is a two tailed test and the significance level is 0.05, that is a = 0.05.

Thus the critical values are z = -1.96 , z = 1.96.

Which implies that the critical region is

`

As the value of the test statics doesn’t lie in the critical region ,

So the null hypothesis can’t be rejected..

Step 7 of 7</p>
