Questions 13 - 17 A supplier of car parts claims to deliver the parts to any manufacturer in a mean time of less than 60 minutes. The population standard deviation is 6.55 minutes. In an effort to test this claim, a manufacturer recorded the times of 43 deliveries from this supplier. The sample mean was 58.6 minutes. At the 5%- level of significance, can we conclude from the data in this sample that the supplier's claim to deliver in less than 60 minutes is correct? 13. Establish the null and the alternative hypotheses. A H, µ # 60, H, : µ< 60 B H, :µ > 60, H,: H< 60 C H :µ= 60, H,:µ> 60 !! E Ho:u= 60, H,4< 60
