A. Reject the null hypothesis; the critical value is 1.645.
B. Fail to reject the null hypothesis; the critical value is 2.00.
C. Reject the null hypothesis; the critical value is 2.10.
D. Fail to reject the null hypothesis; the critical value is 1.96.
A researcher conducts a one-tailed z-test to determine if the average
weight of a new species of bird is greater than 200 grams. After
analyzing the data, the researcher calculates a z-test statistic of 2.10.
The significance level is set at 0.05. What should the researcher
conclude based on the critical value for this test?
Let Zo05 = 1.645, Zo.o25 = 1.96.
