The manager of the quality department for a tire manufacturing company wants to know the average tensile strength of rubber used in making a certain brand of radial tire. The population is normally distributed and the population standard deviation is known. The manager uses a z test to test the null hypothesis that the mean tensile strength is less than or equal to 800. The calculated z test statistic is a positive value that leads to a p-value of .067 for the test.
-If the significance level is .05,the null hypothesis would be rejected.
