- A blogger claims that U.S. adults drink an average of five 8-ounce glasses (that's 40 ounces) of water per day. Researchers wonder if this claim is true, so they ask a random sample of 24 U.S. adults about their daily water intake. A graph of the data shows a roughly symmetric shape with no outliers. We want to test Ho: μ = 40 Ha: μ # 40 a. where μ = the true mean number of ounces of water that a U.S. adult drinks per day. The 90% confidence interval for the mean daily water intake is 30.35 to 36.92 ounces. Based on this interval, what conclusion would you make for a test of the given hypotheses at the a = 0.10 significance level? We fail to reject Ho) at the a = 0.10) significance level. We do not have convincing evidence that the mean daily water intake is different from 40 ounces. We reject Ho) at the a = 0.10) significance level.

- Thomas wants to compare the mean concentration of carbon monoxide (CO) on residential versus commercial streets, since these differ in terms of car traffic. In each of three neighborhoods of Montréal (named A, B, and C below), he randomly chooses four locations for each type of street, for a total of 24 observations (2 street types x 3 neighborhoods x 4 locations). At each location, he measures CO concentration in the air over a period of 10 hours (8:00 AM-6:00 PM), and obtains the following data (in ppm/h). Question: Test whether or not the difference between residential and commercial streets in mean atmospheric CO concentration is the same among the three neighborhoods, and whether or not CO concentration in the air is the same, on average, for the two types of streets. Note that Neighborhood is considered a random block factor in the ANOVA.
