1. a. A major department store chain manager believes that more than one third of its credit card customers spent at least S50 on their first visit to the chain's new store in the mall. 250 credit card accounts were randomly sampled and found that 156 of these account holders spent less than or equal to $50 on their first visit to the chain's new store in the mall. At the 3% level of significance, does this sample provide sufficient evidence that more than one third of its credit card customers spent at least $50 on their first visit to the chain's new store in the mall? State the null and the alternative hypotheses. What is your conclusion?
