To find the P-value, you must first find the standardized score. STA 2e: Sect. 9.2 Worksheet #2. The formula is: For #11 – 16: If a die is fair, then the number 5 should occur 1/6 of the time. You have a die that you suspect is loaded so that the number 5 lands face up more often then expected. You roll the die 200 times and get 45 5's.

Find the P-value for a left-tailed test with a test statistic of z = -2.23. Decide whether to reject H0 if the level of significance is α = 0.01. From the normal table z = -2.23 is P= 0.0129 which is the area in the left tail. Since 0.0129 > 0.01, you should fail to reject H0. Find the P-value for a two-tailed test with test statistic of z = 2.14.

The standardized observed test statistic is: When you test hypotheses by using the t test (traditional method), follow the same procedure as for the z test, except use The T-test using Table F. Step 1 State the hypotheses and identify the claim. Step 2 Find the critical value(s) from Table F.

The standardized values using the sample standard deviation sx in place of the population standard deviation σ, show much greater spread. In fact, in a few samples, the statistic: took values below −6 or above 6. This statistic has a distribution that is new to us, called a t distribution.
