and 1- area below and in the upper tail. For the t distribution, the text . Table T. and . Excel functions. use tail probabilities, hence . t denotes a table value with in the upper tail. For 2-tail procedures, = area in two tails and /2 = the area in one tail, hence . t /2 . is the notation. For 1 tail procedures, is the area in one tail.

Look at the ‘critical t’ for a one-tailed test in the printout. This is the value given for p = 0.1 in a t-table (because we are testing only for a difference in one direction - above zero - so we can double the normal probability of 0.05). We should have used this value, not the value for …

H0: HA: We have a small-sample test, so we’ll get our critical value from the t-table. We have one tail, alpha = 0.05, and 12 degrees of freedom, so the critical t-value will be 1.782. If the value of our test statistic is greater than 1.782, then we will reject the null hypothesis. Our test statistic is: We do not reject the null hypothesis.

3. In the t table on the row for df = 13 and one-tail (, t =1.771. The rejection region is t < - 1.771. 4. Since – 3.026 < -1.771 H0 is rejected. 5. There is enough evidence at the 5% level of significance to reject the claim that the mean price of a Nimbus SUV is at least $23,900.
