A researcher is ivestigating whether a reading intervention program improves reading comprehension for second graders. She collects a random sample of second graders and randomly assigns each second grader to participate in the reading intervention program or not participate in the program. The researcher knows that the standard deviation of the reading comprehension scores among second graders is o 25.24. Group 1 consists of ni = 52 second graders who did not participate in the program. Their mean reading comprehension score is Mi = 36.8. Group 2 consists of na = 56 second graders who did participate in the program. Their mean reading comprehension score is Ma = 52.4. or the plots that follow, which best represents a plot of these results? O Plot B O Plot A O Plot C O Plot D Plot A Plot B go2 Plot C

Transcribed Image Text:A researcher is investigating whether a reading intervention program improves reading comprehension for second graders. She collects a random
sample of second graders and randomly assigns each second grader to participate in the reading intervention program or not participate in the
program. The researcher knows that the standard deviation of the reading comprehension scores among all second graders is o = 25.24.
Group 1 consists of ni = 52 second graders who did not participate in the program. Their mean reading comprehension score is Mi = 36.8. Group 2
consists of na = 56 second graders who did participate in the program. Their mean reading comprehension score is Ma = 52.4.
