The mean age of bus drivers in Chicago is 49.6 years. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis? B O A. There is not sufficient evidence to support the claim u = 49.6. Given Ho: H = 25, Ha: H #25, and P = 0.031. Do you reject or fail to reject Ho at the 0.01 level of significance? O B. There is sufficient evidence to support the claim u = 49.6. 15. O C. There is sufficient evidence to reject the claim u = 49.6. O D. There is not sufficient evidence to reject the claim u = 49.6. O A. reject Ho O B. fail to reject Ho O C. not sufficient information to decide Test the claim about the population mean u at the level of significance or. Assume the population is normally distributed. Claim: [ > 18; a = 0.05; o = 1.2 Sample statistics: x = 18.3, n = 50 14. O A. Reject Ho. There is enough evidence at the 5% level of significance to support the claim. O B. Fail to reject Ho. There is not enough evidence at the 5% level of significance to support the claim. O C. There is not enough information to decide
