Question: Find the test statistic and critical value. Also use the chi-square distribution to find limits containing the p-value and then determine whether there is sufficient evidence to support the given alternative hypothesis.
- standard deviation of all values in a population does not equal 0.25
- alpha = 0.01
- number of values in a sample = 26
- standard deviation of a set of sample values = 0.18
We can compute the chi-squared test statistic as ...
