Researchers studied the impact of cooking on the prevalence of fine particles in the air. The decay rate (measured in µm/hr of fine particles produced from oven cooking was recorded on six randomly selected days. The measurements were:

[0.95, 0.83, 1.20, 0.89, 1.48, 1.13]

(A) Find the quick-and-dirty 95% confidence interval for the average decay rate of fine particles produced from oven cooking. Show work.

(B) Find a 99% confidence interval, without using an applet, for the average decay rate of fine particles produced from oven cooking. Show work.

(C) Suppose we want to estimate the average decay rate at a confidence level of 99% to within plus or minus 0.1. What sample size should we expect to need? Show work.
