Question 5 0/3 pts 5399 Details You wish to test the following claim (H) at a significance level of a = 0.02. Hu = 50.7 H: #50.7 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 410 with mean M = 46.7 and a standard deviation of SD = 20.7. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null accept the null fail to reject the null As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 50.7. There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 50.7. The sample data support the claim that the population mean is not equal to 50.7. There is not sufficient sample evidence to support the claim that the population mean is not equal to 50.7.

Answer 1

Solution- Sd=20.7. Given ne 410 „Mis 46.7, Test Hypothesis! Ho: u= 50.7 Ha! U 50.7 Test Statistics: M-M 46.750.7 Z= 2-3.9127 SD 2017 1410 Z=-3.9127 P values Z-3.9127 using z distribution two tail table pvalue=0.00009 At p value <a Null decision- Reject the loption is right auswas
