A grocery store is interested in determining whether or not a difference exists between the shelf life of two different brands of doughnuts. A random sample of 100 boxes of each brand was selected and the shelf life in days was determined for each box. The sample results are given below.
Brand A
Brand B
Mean (x-bar) = 2.1
Mean (x-bar) = 2.9
s = 0.8
s = 1.1
n = 100
n = 100
Find a 90% confidence interval for μA - μB, the difference in mean shelf life between brand A and brand B. Assume that the assumptions and conditions for inference have been met.
