Describe type I and type II errors for a hypothesis test of the indicated claim. A lumber store claims that at least 25 % of its new customers will return to buy their next order of lumber . Describe the type I error. Choose the correct answer below. A. A type I error will occur when the actual proportion of new customers who return to buy their next order of lumber is at least 0.25 , but you reject Upper H 0 : pgreater than or equals 0.25 . B. A type I error will occur when the actual proportion of new customers who return to buy their next order of lumber is no more than 0.25 , but you reject Upper H 0 : pless than or equals 0.25 . C. A type I error will occur when the actual proportion of new customers who return to buy their next order of lumber is at least 0.25 , but you fail to reject Upper H 0 : pgreater than or equals 0.25 . D. A type I error will occur when the actual proportion of new customers who return to buy their next order of lumber is no more than 0.25 , but you fail to reject Upper H 0 : pless than or equals 0.25 . Describe the type II error. Choose the correct answer below. A. A type II error will occur when the actual proportion of new customers who return to buy their next order of lumber is more than 0.25 , but you fail to reject Upper H 0 : pgreater than or equals 0.25 . B. A type II error will occur when the actual proportion of new customers who return to buy their next order of lumber is less than 0.25 , but you fail to reject Upper H 0 : pgreater than or equals 0.25 . C. A type II error will occur when the actual proportion of new customers who return to buy their next order of lumber is more than 0.25 , but you reject Upper H 0 : pless than or equals 0.25 . D. A type II error will occur when the actual proportion of new customers who return to buy their next order of lumber is less than 0.25 , but you reject Upper H 0 : pless than or equals 0.25.
