Consider Case Study 4.2 on page 170. Suppose 18 specimens were used for each type of paint

Question:

Consider Case Study 4.2 on page 170. Suppose 18 specimens were used for each type of paint in an experiment andIB TA-ĪB, IA the actual difference in mean drying time, turned out to be 1.0.
(a) Does this seem to be a reasonable result if the two population mean drying times truly are equal? Make use of the result in the solution to Case Study 4.2.
(b) If someone did the experiment 10,000 times under the condition that μA=μB, in how many of those 10,000 experiments would there be a differenceIA that was as large as (or larger than)1.0?
