Find the test statistic, find the critical values of x2 and limits containing P-value

Find the test statistic, find the critical values of x2 and limits containing P-value, then determine whether there is sufficient evidenceto support the given alternative hypothesis

H1: variance is not equal to 18, alpha = 0.05, n =25, s = 22

Determine the test statistic (round to nearest thousandth)
Use a chi square table to determine the critical values
Enter lower value first. ___ ___(round to thousandth)

Choose one:
a. There is sufficient evidence to support the claim
b. There is not sufficient evidence to support the claim
