Determine whether the standardized test statistic t indicates that you should reject null hypothesis. Explain
a. T=1.506
b. t=0
c. T=-1.368
d. T=-1.483
P-values In Exercises 17–20, do the following:
a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.
b. Find the P- value. (See Figure 8-3 on page 364.)
c. Using a significance level of α = 0.05, should we reject H0 or should we fail to reject H0?
The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3.
State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain.
(a) t =1.667
(b) t =0
(c) t= -1.552
