In each of Exercises, we have provided a sample standard deviation and sample size. In each case, use the onestandarddeviation χ2-test and the one-standard-deviation χ2-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval.

s = 7 and n = 26

a. H0: σ = 5, Ha: σ > 5, a = 0.01

b. 98% confidence interval

Step 1

**a).**

The sample standard deviation and the sample size are, *s* = 7 and *n* = 26 respectively. The significance level is 0.01. The hypothesis to be tested is,

The null and alternative hypotheses are given below:

Step 2

Decision rule:

Reject the null hypothesis if

Step 3

The test is to be performed at 1% level of significance.

The value o...
