A watch maker claims that the weekly error in their watches has standard deviation of 1 second. sample of 20 watches yields a sample standard deviation of significance level, do the data support the hypothesis that the standard deviation of the weekly error of the watches exceeds the 1 second claimed by the manufacturer? Formulate and carry ou s = 1.364 seconds. At the 1% the appropriate chi-square test. The null hypothesis is Ho . o = 1 0gnin include answers to a)-d) as in the previous hypothesis tests.
