A company sells 25 g boxes of sultanas that are promoted as a healthy snack food option for children. The company wants to estimate the number of sultanas packed into a box. To do so, a random sample of 30 boxes of sultanas is selected during a production run. The number of sultanas in each box is counted. Using this sample, the average number of sultanas per box is calculated to be 50.3. If the standard deviation is known to be 1.2 sultanas per box, what is the point estimate of the number of sultanas per box? Construct a 95% confidence interval to estimate the mean number of sultanas packed per box during the production process.
