Appendix A Statistical Tables

a. Use the data given to test the following hypotheses.(Round your answer to 2 decimal places, e.g. 15.25.)

The value of the test statistic is

enter the value of test statistic rounded to 2 decimal places

and we

select a decision

reject the null hypothesis

fail to reject the null hypothesis

.

b.Use thep-value to reach a statistical conclusion.(Round your answer to 4 decimal places, e.g. 0.1254.)

Since thep-value of

enter an appropriate value rounded to 4 decimal places

is

select an option

greater

less

than /2 = .005, the decision is to:

select a decision

reject the null hypothesis

fail to reject the null hypothesis

.

c.Using the critical value method, what are the critical sample mean values?(Round your answer to 3 decimal places, e.g. 15.254.)

Critical mean values:

Upper value:

enter the upper mean value rounded to 3 decimal places

Lower value:

enter the lower mean value rounded to 3 decimal places
