The accuracy of a coin-counter machine is gauged to accept nickels with a mean diameter of millimeters 21.21 mm. A sample of 41 nickles was drawn from a reported defective coln-counter machine located near a school. The sample had a sample mean of 21.211 mm and sample standard devlation 0.011 mm. Test the claim that the mean nickel diameter accepted by this coin-counter machine is greater than 21.21 mm. Test at the 0.01 significance level. (a) Identify the correct alternatve hypothesis H: Ομ< 21.21 Ομ> 21.21 = 21.21 Glve all answers correct to 4 decimal places. (b) The test statistic value is: (C) Using the Traditional method, the critical value is(round to 2 decimal places) :
