Question

1. The owner believes that more than 50% of all customers who visit the store buy books. Since they don’t keep track of this formally, she does so on a particular day and observes that 34 of the 60 customers who visited also purchased a book.
   1. In your own words, please state why we can’t say for sure that she is correct even though observing more than 50% of customers buying books on the day she tracked it matches with her prediction.
2. 2. Given her observation, and assuming this is a valid, representative sample, can we say with 95% confidence that she is correct? Please perform all six steps for hypothesis testing
