The critical values are generally –z* and +z*. Confidence Interval for a Population Mean (sigma known) Choose an SRS of size n from a population having unknown mean and known standard deviation. A level C confidence interval for is. Here z* is the value that determines the area C between –z* and z* under the standard Normal curve.

Find the critical value for 22 degrees of freedom when = 0.05 and the test is two-tailed. After the degrees of freedom reach 30, the table only gives values for multiples of 10. When the exact degrees of freedom are not specified in the table, the closest smaller value …

Critical value must be t, at 0.05 level of significance and 10 degrees of freedom; n1+ n2 -2 = 5 + 7 -2 = 10. =TINV(0.05,10) = + 2.23. Decision rule: Reject the null hypothesis if t-test from the sample data is larger than 2.23 or smaller than -2.23.

Make sure to write the hypothesis, indicate the test statistics, make a decision specifying the P-value or indicating the critical value, then write your conclusion. (c) (4 pt.) If you reject the null hypothesis, make sure to look at the multiple comparison test and identify the different means)

The critical value separates the critical region from the noncritical region. The symbol for critical value is C.V. The critical or rejection region is the range of values of the test value that indicates that there is a significant difference and that the null hypothesis should be rejected.
