Question 1

Use the information to find the value. Also, use a significance level of 0.05 and state the conclusion about the null hypothesis (reject the null hypothesis or do not reject the null hypothesis).

The test statistic in a two-tailed test is z = -1.63.

0.0516; reject the null hypothesis

0.0516; do not reject the null hypothesis

0.9484; do not reject the null hypothesis

0.1032; do not reject the null hypothesis

Question 7

Find the critical value or values of 2 in the given information. Ho: = 8.0 n = 10 = 0.01

2,088, 21,666

1,735, 23,589

23,209

21,666

Question 10

Suppose the data have a normal distribution and the number of observations is greater than fifty. Find the critical value of z to test the null hypothesis. = 0.09 for a right-tailed test.
