Scores on an exam were compared. 2 Statistic Simulation Tutorial points Mean score 21 = 9.4 202 = 10.6 Sample std. dev. $1 = 2.4 $2 = 2.5 Number of students n1 = 25 n2 = 25 e Book References a. Construct a 95 percent confidence interval for the true difference in mean scores. (Round your answers to 2 decimal places. Negative values should be indicated by a minus sign.) The 95% confidence interval is from to b. Do you think the learning methods have significantly different results?

Return to question 5 A newly installed automatic gate system was being tested to see if the number of failures in 1,000 entry attempts was the same as the number of failures in 1,000 exit attempts. A random sample of eight delivery trucks was selected for 2 data collection. Do these sample results show that there is a significant points difference between entry and exit gate failures?
