in the critical region
not in the critical region
This test statistic leads to a decision to...
reject the null
accept the null
fail to reject the null
As such, the final conclusion is that...
There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.6.
There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.6.
The sample data support the claim that the population mean is not equal to 69.6.
There is not sufficient sample evidence to support the claim that the population mean is not equal to 69.6.
You wish to test the following claim (He) at a significance level of ? 0.01. Ho: ? : 69.6 Ha H69.6 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n- 26 with a mean of M -80.8 and a standard deviation of SD 17.9 What is the critical value for this test? (Report answer accurate to three decimal places.) critical valuet What is the test statistic for this sample?

There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.6. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.6. The sample data support the claim that the population mean is not equal to 69.6 There is not sufficient sample evidence to support the claim that the population mean is not equal to 69.6.Explanation / Answer
Critical value = +/- 2.576
test statistics:
t = (x -mean)/(s/sqrt(n))
= (80.8 - 69.6)/(17.9/sqrt(26))
= 3.190
the test statistics is in the critical region
Reject teh null hypothesis
There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.6.
