If your critical value is ±±1.6 then you are running a:
If your critical value is ±±1.6 and the test statistic is 3.9 you
would:
If your critical value is ±±1.6 and the test statistic is 3.9 you
would be:
If your critical value is ±±1.8 then you are running a:
If your critical value is ±±1.8 and the test statistic is -4.5 you
would:
If your critical value is ±±1.8 and the test statistic is -4.5 you
would be:
Two tailed test
As the critical value has both +1.6 and -1.6 we would have two tailed test.
reject the Ho
As the obtained test statistic is greater than critical value we would reject Ho.
able to show that the average was greater than claim.
As the test statistic value is greater than both the critical values.
two tailed test
As it contains both the critical values that is +1.8 and -1.8.
Reject the Ho
As the test statistic is less tthan -1.8 we would reject Ho.
able to show that average is less than claim
As the test statistic value is less than -1.8 we can claim it is less than claim.
