Students played the memory game and recorded how long it took to finish the game. Here is the data

1st Period- 30 students finished in an average time of 106.93 sec with a standard deviation of 27.24

4^th Period- 35 students finished in an average time of 102.82 sec with a standard deviation of 23.16

1. Construct and interpret a 90% confidence interval for the true difference (1st Period -4th Period) in average time it took to complete the memory game..

Stat Test 0

1. Do the data provide convincing evidence that 4th period students finished faster , on average, than 1st period students? Use a = 0.10

Stat --. Test 4

1. Ultimately based on the intervals and tests done above for both the trivia questions and the memory game, which class is smarter? Justify your answer using some of the data and conclusions above.
