Question:
In your answer include:
The mathematical formulas for the null and alternative hypotheses
Your z-score calculated three decimal places
The boundary value you used for the rejection region
The three part conclusion statement as discussed in class (1. reject null: true or false?, 2: context from our research question, 3: how sure are you about your results?)
If you use a t-distribution with degrees of freedom = 40 and rejection region boundary of -1.303, does your conclusion change?
Hint 1: the observations in this case are "days" not "people"
Hint 2: you case use the approximation that the standard deviation of a set of data is approximately equal to the range of the data / 6. This is based on the idea that 99% of observations in a normally distributed set of data fall between +/- 3 standard deviations of the mean.
