[hi Consider the pairwise differences it; - Hm pg p5 . and pic - #3.. Find a point estimate of and a Tukey simultaneous 95 percent condence intenral for each pairwise difference. Interpret the results in practical terms. Which bottle design maximizes mean daily sales? {Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign] - [c] Find a 95 percent condence interval for each of the treatment means an: #3, and Ho Interpret these intervals. [Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.} A consumer preference study compares the effects of three different bottle deslgns {24. B, and C} on sales of a popular fabric softener. A completely randomized design is employed. Specically, 15 supermarkets of equal sales potential are selected. and 5 of these supermarkets are randomly assigned to each bottle design. The number of bottles sold in 24 hours at each supermarket is recorded. The data obtained are displayed in the following table. 15 32 20 13 32 26 14 32 24 19 35 26 16 35 25 The Excel output of a one-way ANDVA of the Bottle Design Study Data is shown below.
