Research results suggest a relationship between the TV viewing habits of 5-year-old children and their future performance in high school. For example, Anderson, Huston, Wright, and Collins (1998) report that high school students who regularly watched Sesame Street as children had better grades in high school than their peers who did not watch Sesame Street. Suppose that a researcher intends to examine this phenomenon using a sample of 20 high school students. The researcher first surveys the students' parents to obtain information on the family's TV viewing habits during the time that the students were 5 years old. Based on the survey results, the researcher selects a sample of n = 10 students with a history of watching Sesame Street and a sample of n = 10 students who did not watch the program. The average high school grade is recorded for each student and the data are as follows: Watched Sesame Street 86 87 91 97 98 99 97 94 89 92 n = 10 M = 93 SS=200 Average High School Grade Did Not Watch Sesame Street 90 89 82 83 85 79 83 86 81 92 n = 10 M = 85 SS = 160 Use an independent t test with an alpha of .05 to determine whether there is a significant difference between the two types of high school students.
