A test is made of Ho : V -135 vs. Ha : V < 135 A sample of size 63 is drawn and -130. The population standard deviation is 40. Test the hypothesis at 10% significance level. Some parts need Rguroo. Refer to the activity instructions for guidance. b) The observed z-statistic and the z-critical . Round answers to three decimal places. c) For < d) P-value , we can reject the null. Round answers to three decimal places. which is (choose > , < or z) than the significance level of 10%, we do not have suffcient evidence to reject the null. Round answer to the p-value to three decimal places.
