Question: Does it ever seem to you that the weather is nice during the work week, but lousy on the weekend? Cerveny and Balling (1998) have

Does it ever seem to you that the weather is nice during the work week, but lousy on the weekend? Cerveny and Balling (1998) have confirmed that this is not your imagination-pollution accumulating during the work week most likely spoils the weekend weather for people on the Atlantic coast. Consider the following hypothetical data showing the daily amount of rainfall for 10 weeks during the summer.

a. Calculate the average daily rainfall (the mean) during the week, and the average daily rainfall for weekends.
b. Based on the two means, does there appear to be a pattern in the data?

Average Daily Rainfall on Average Daily Rainfall on Weekends (Sat.-Sun.) Weekdays (Mon.-Fri.) Week 1.2 1 1.5 0.6 0.0 2.0 3 1.8 4 1.6 1.5 0.8 2.2 6. 2.1 2.4 0.2 0.8 8. 0.9 1.6 1.1 1.2 10 1.4 1.7
