Problem 3E

(In some of the exercises that follow, we must make assumptions, such as normal distributions with equal variances.)

We wish to compare compressive strengths of concrete corresponding to a = 3 different drying methods (treatments). Concrete is mixed in batches that are just large enough to produce three cylinders. Although care is taken to achieve uniformity, we expect some variability among the b = 5 batches used to obtain the following compressive strengths (there is little reason to suspect interaction; hence, only one observation is taken in each cell):

(a) Use the 5% significance level and test HA: α1 = α2 =α3 = 0 against all alternatives.

(b) Use the 5% significance level and test HB: β1 = β2 =β3 = β4 = β5 = 0 against all alternatives. (See Ledolter and Hogg in References.)

The answer to “(In some of the exercises that follow, we must make assumptions, such as normal distributions with equal variances.)We wish to compare compressive strengths of concrete corresponding to a = 3 different drying methods (treatments).

Although care is taken to achieve uniformity, we expect some variability among the b = 5 batches used to obtain the following compressive strengths (there is little reason to suspect interaction; hence, only one observation is taken in each cell): (a) Use the 5% significance level and test HA: ?1 = ?2 =?3 = 0 against all alternatives.(b) Use the 5% significance level and test HB: ?1 = ?2 =?3 = ?4 = ?5 = 0 against all alternatives.
