Six measurements were made of the concentration (in percent) of ash in a certain variety of spinach.

Question:

Six measurements were made of the concentration (in percent) of ash in a certain variety of spinach. The sample mean was 19.35 and the sample standard deviation was 0.577. Assume that the concentrations are normally distributed.

a. Find a 90% prediction interval for a single measurement.

b. Find a tolerance interval for the pH that includes 99% of the measurements with 95% confidence.
