Assume a normal distribution and use a hypothesis test to test the given claim According to city reports, it was found that the mean age of the prison population in the city was 26 years. He obtains a random samplo of 25 prisoners and finds a mean age of 24.4 years and a standard 20. years. Marc wants to test the claim that the mean age of the prison population in his city is less than 26 deviation of 9.2...

In order to conduct a hypothesis test for the population mean, a random sample of 24 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 6.3 and 2.5, respectively. (You may find it useful to reference the appropriate table: z table or t table). H0: μ ≤ 5.1 against HA: μ > 5.1 a-1. Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal...

If, in a one-tail hypothesis test, the p-value=0.5122 what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? A) Since the p-value is less than α=0.07, do not reject H0. B) Since the p-value is greater than or equal to α=0.07, do not reject H0. C)Since the p-value is greater than or equal to α=0.07, reject H0. D) Since the p-value is less than α=0.07, reject H 0...
