Question

Use a chi squared test to test the claim <43 at the .01 significance level Using the sample statistics S = 38.7 and n= 21. Assume the population is normally distributed.

I want to make sure I have the critical value correct of 37.566.  The other option (if I'm using the wrong tailed table) would be 8.26.  That would then give me the correct conclusion, which I always seem to get incorrect! Please help!

Use a x²-test to test the claim o<43 at the a = 0.01 significance level using sample statistics s = 38.7 and n = 21.
Assume the population is normally distributed.
OC. Ho: o>43
Ha: o≤43
Identify the standardized test statistic.
16.2 (Round to three decimal places as needed.)
Identify the critical value(s).
37.566
(Round to three decimal places as needed. Use a comma to separate answers as needed.)
Choose the correct conclusion below.
O A. Fail to reject Ho. There is not enough evidence at the 1% level of significance to support the claim.
B. Fail to reject Ho. There is enough evidence at the 1% level of significance to support the claim.
O C. Reject Ho. There is enough evidence at the 1% level of significance to support the claim.
OD. Reject Ho. There is not enough evidence at the 1% level of significance to support the claim.
