Question

Research results suggest a relationship between TV viewing habits of 5-year old children and their future performance at high school. Wright and Collins (1998) reported that children who regularly watched Sesame Street as children receives better grades than those had not watched the show as children. Suppose another researcher wants to replicate this study on 20 high school children. The researcher first surveyed the parents of the students to obtain information about their TV viewing habits during the times that the students were 5 years old. Based on the survey results researcher selects a sample of n=10 with a history of watching Sesame Street and n=10 that did not watch the program. The average high school grade is recorded for each student and the data are as follows:

Watched Sesame Street	Didn't Watch Sesame Street
86	90
87	89
91	82
97	83
98	85
99	79
97	83
94	86
89	81
92	92

How would the researcher test if there were a significant difference between the two groups of students? Use JASP to conduct an independent sample t-test. Write all the steps of hypothesis testing using t-test (as shown in the handout) and attach the document (WORD DOC) here.
