(Scenario 2) Mickey is interested in the average amount of water a broom carrying water buckets could pour into a cistern. It is believed that the amount of water carried is approximately normal. A random sample of 28 water buckets was taken and it was found that, on average, each bucket could hold 4.8 gallons of water, with a standard deviation of 0.2 gallons. A 92% confidence interval was created.

Answer scenario 2

2. For the following scenarios, identify whether you should use \( z \) or \( t \) in a confidence interval calculation. (You don’t have to do anything else.)

**(Scenario 1)**  
Minnie owns a boutique that sells hair-bows and bow-ties. On a normal day, Minnie makes many sales. The average selling price is approximately normally distributed with a standard deviation of $0.72. Minnie is interested in the average selling price of products sold on one day. A sample of 36 sales were investigated from that day, and it was found that the average selling price was $4.78. A 93% confidence interval was created.
