Chapter 12.1, Problem 3E
In 2014, the University of Houston carried out a study for the Texas Lottery Commission (“Demographic Survey of Texas Lottery Players”) that gives the age distribution for a representative sample of 375 Texas Lottery players.
Using data from the U.S. Census Bureau (census.gov) for 2014, the age distribution of adults in Texas was 14% between age 18 and 24, 20% between age 25 and 34, 19% between age 35 and 44, 18% between age 45 and 54, 14% between age 55 and 64, and 15% age 65 or older. Is it reasonable to conclude that one or more of the age groups buys a disproportionate share of Texas Lottery tickets? Use a chi-square goodness-of-fit test with α = 0.05.
(Hint: See Example 12.2.)

- It is thought that prehistoric Native Americans did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.50 6.00 6.75 7.00 7.75 y 37 38 92 70 99 Find the equation of the least squares line .
