Test for population standard deviation at 5% level

Make use of the traditional method with α = 0.05 to test the claim that the weights of statistic textbooks vary more than the weights of text in general: σ = 0.65kg. A simple random sample of 8 statistic text, taken from a normally distributed population, was found to have a standard deviation of 0.72kg. Compute the test statistic and the critical value to determine the conclusion. Regarding this claim.

Establish the test statistic ___________ (Round to nearest thousandth).
Make use of the Chi-Square distribution table to determine the critical value. (Round to the nearest thousandth)
select the correct conclusion regarding the claim that the weights of statistics text vary more than the weights of text in general.

A). Reject the null hypothesis; there is sufficient evidence to support the claim.
B). Fail to reject the null hypothesis; there is insufficient evidence to support the claim.
