1.Business survey:

In order to understand why consumers visit their store, a local business conducts a survey by asking the next 100 people who visit their store to fill out a short survey. The business finds that 41 of the 100 people state that the main reason they visited the store was because the store is running a sale on coats that week.

a)The store manager had conjectured that at least 30% of customers would visit for the sale. Test whether the store manager's conjecture was correct. As you work, tell me:

i.What are your null and alternative hypotheses? Make sure to define your parameter.

ii.What is your p-value and standardized statistic? You'll assess the strength of evidence by using Minitab.

b)Use Minitab to compute a 99% confidence interval for the parameter of interest.
