This question demonstrates the relationship between hypothesis testing and confidence intervals.
95% confidence interval from #6:(19.1 , 21.6 )
Choose 4 values for 0 to use in this exercise, as follows. Choose 2 values from within the above confidence interval, 1 value slightly outside the interval to the left, and 1 value slightly outside the interval to the right.Fill these in the table below.
Use your data and the calculator (2:T-Test,) to testfor these 4 values of 0.
Test at the = .05 level.For each value chosen, in the table below, give the P-value of the test and say whether your conclusion would be "Reject H0" or "Fail to Reject H0". (NOTE:This should go quickly.All you have to do is change the in 2:T-Test, and then re-calculate the P-value.)
Table:
Description of value | 0 | P-value of test | Conclusion:Reject H0 or Fail to Reject H0
A value within interval |
A value within interval |
A value just outside the |
lower limit of interval
A value just outside
the upper limit of interval |
In your own words, what have you demonstrated about the relationship between a (1-) confidence interval and a two-tailed hypothesis test run at the -level?(This should be a generalized conclusion.)
