A random sample of n = 25 freshmen is selected from the State College. All 25 students are placed in the new English composition course during their first semester. One year later, a writing sample is obtained for each student and their writing samples are graded using a standardized evaluation technique. The average score for the sample is M= 76. For the general population of the State College, writing scores form a normal distribution with a mean = 70 and a standard deviation = 20. Please calculate the appropriate hypothesis test using all four steps?Description of Data This data set contains the achievement test (English as a Second Language) results and some background data collected during experimental trial of a new ESL program. The study was one year in duration. Students were allocated to the experimental ESL program class and a regular program control class on a random basis. Vocabulary and grammar tests were administered to the students in both groups at the beginning and the end of the school year. Data can be found in the pic uploaded Variables The dataset includes 24 cases and 7 variables: ▪ Student ID ▪ Group (1 - experimental, 2 - control) ▪ Gender (1 - male, 2 - female) ▪ Pre-test vocabulary scores (scores range from 0 - 25) ▪ Pre-test grammar scores (scores range from 0 - 25) ▪ Post-test vocabulary scores (scores range from 0 - 25) ▪ Post-test grammar scores (scores range from 0 - 25) 1.
