Self-confidence experiment description Dr. Confit had noticed that many of his high school students seemed to lack confidence in their abilities. He read about an educational program designed to increase students' self-confidence, so he decided to administer it to all of the seniors that year. By a major stroke of luck, seniors in the past 20 years had completed a validated measure of self-confidence in their AP Psychology class, so he had scores for the population of past seniors on the same measure he would use to assess the sample on whom he was going to try out the program. The mean self-confidence score in the population of past seniors was 8. Dr. Confit was very confident that the seniors experiencing the program this year would indeed achieve a higher level of self-confidence than the seniors in the past had, so he used a one-tailed test. This year's senior class was very small, consisting of only 6 students, and their scores when they eventually took the self-confidence measure in the last week of school are listed below. Question 44 (1 point) l 1:)Listen bl Which is/are being used in this study? l a] one sample is being compared to a population whose mean is known, so a one-sample ttest will be used to compare the conditions. b) two independent samples are being compared, so an independent-samples t test will be used to compare the conditions c) two matched samples are being compared, so a dependent-samples ttest will be used to compare the conditions d) the same participants are experiencing both conditions, so a dependent- samples ttest will be used to compare the conditions Question 45 (0.2 points) l 1:)Listen bl Based on the description of Dr. Confit's experiment above, identify u: Question 46 (0.2 points) ' (1) Listen b ' Based on the description of Dr. Confit's experiment above, identify n: \\ ex Question 47 (2 points) ' 41) Listen b ' State your ALTERNATIVE research hypothesis.
