Describe the study Mary might plan where she would use a one-way analysis of variance (ANOVA) for independent groups instead of a t-test to study differences between noise levels. 1. What is her independent variable here?
2. Describe the conditions she could create for this study. What is her dependent variable?
3. Describe a way to measure the DV so that each participant would have one score at the end that would be on a continuous scale of measurement.

Three runners competed in a race data were collected at each mile mark for each runner if the runner ran at a constant pace the data would be linear

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
