Suppose we would like to determine if the typical amount spent per customer for dinner at a new restaurant in town is more than $20.00. A sample of 49 customers over a three-week period was randomly selected and the average amount spent was $22.60. Assume that the standard deviation is known to be $2.50. Using a 0.02 level of significance, would we conclude the typical amount spent per customer is more than $20.00?

Suppose that we want to determine whether or not amount of light exposure is linked to depression. We identify 5,000 participants across the United States with no intention of moving to a different permanent residence within the next two years and classify them as living in an area with high or low light exposure. We exclude those who are experiencing depression symptoms at baseline. We then follow them up for two years and determine whether they have experienced depression since...
