4. In 2014, the University of Houston carried out a study for the Texas Lottery Commission. The accompanying table gives the age distribution for a representative sample of 375 Texas Lottery players. Age Group Frequency 18 to 24 25 to 34 32 35 to 44 34 45 to 54 60 55 to 44 106 65 and older Total 136 375 Using the data from the U.S. Census Bureau 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 54 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 = 0.05.
