Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a…

Chapter 10.2, Problem 39E

a.

To determine

Check whether there is evidence to support claim that mean compression increases with the temperature at the storage condition or not.

b.

To determine

Obtain a 95% confidence interval for the difference in the mean compression for the two temperatures.

c.

To determine

Check whether the 95% confidence interval consists zero or not.

Explain the connection with the conclusion of part (a).

d.

To determine

Check whether the normal probability plots of compression indicate any violations of the assumptions for the tests and confidence interval or not.
