b.) State the null and the alternative hypotheses and identify the claim

c.) Use invT to find the critical z-value or values based on the significance level. Round to two decimal places

d.) Draw a diagram of the critical area or areas. Label the critical t-value, t0 or critical t-values, -t0 and t0, rounded to two decimal places

e.) State the t-value or test statistic based on the calculation found using TTest

f.) Draw the position of the test statistic (or t-value) on your diagram. State the p-value

g.) Decide whether to reject or fail to reject the null. State your reasons why.
