Answer #1

One-way repeated measures ANOVA

Explanation:

For the given scenario, we have to compare the three groups or three different types of novel computer keyboard designs. So, we need to use the one way ANOVA test. The observations for the three groups are produced due to same subjects. This means, same participants were used for taking results from three groups. So, each participant is repeated three times and generates three observations for three groups. So, we need to use one-way repeated measures ANOVA.

A human factors psychologist is interested in how alcohol impacts driving performance. A sample of participants was randomly assigned into one of three different conditions of alcohol blood levels (abl). The participants then operate a driving simulator and each participant was measured on how much time (in seconds) they spent on a target when steering. The more time they spend on a target, the better their driving skills. What can the psychologist conclude with α = 0.05? abl 1 abl...

A consumer preference study compares the effects of three different bottle designs (A, B, and C) on sales of a popular fabric softener. A completely randomized design is employed. Specifically, 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. Bottle Design Study Data A B C 17...
