# Question: Parkrose Bakery bakes large batches of rolls in huge ovens

Parkrose Bakery bakes large batches of rolls in huge ovens. The bakers require that halfway through each baking cycle, the average temperature for the rolls in the batch be 325oF. A higher or lower average batch temperature will require an adjustment in the oven setting. To check this condition, a random sample of 36 rolls is selected halfway through each cycle and the sample average temperature is calculated.

a. If a sample has a mean temperature of 323.4o, compute the p-value for the sample result. Assume a population standard deviation of 4.5o.

b. If the significance level is 1%, can the null hypothesis be rejected? Explain.
