Describe type I and type II errors for a hypothesis test of the indicated claim.
A clothing store claims that at least 80% of its new customers will return to buy their next article of clothing.
Describe the type I error. Choose the correct answer below.
OA. A type I error will occur when the actual proportion of new customers who return buy their next
article of clothing is at least 0.80, but you reject Ho: p20.80.
OB. A type I error will occur when the actual proportion of new customers who return to buy their next
article of clothing is at least 0.80, but you fail to reject Ho: p20.80.
OC. A type I error will occur when the actual proportion of new customers who return
article of clothing is no more than 0.80, but you fail to reject Ho: p≤0.80.
OD. A type I error will occur when the actual proportion of new customers who return
article of clothing is no more than 0.80, but you reject Ho: p≤0.80.
