Extracted text: Quiz vs Lecture Pulse Rates Do you think your pulse rate is higher when you are taking a quiz than when you are sitting in a lecture? The data in Table 6.23 show pulse rates collected from 10 students in a class lecture and then from the same students during a quiz. The data are stored in QuizPulse10. Construct a 95% confidence interval for the difference in mean pulse rate between students in a class lecture and taking a quiz. Table 6.23 Quiz and lecture pulse rates for 10 students Student 1 2 4 6. 7 8 10 Mean Std. Dev. Quiz 75 52 52 80 56 90 76 71 70 66 68.8 12.5 Lecture 73 53 47 88 55 70 61 75 61 78 66.1 12.8


Extracted text: Testing for a Difference in Pulse Rates Exercise 6.250 describes pulse rates collected from 10 students, once during a quiz and once during a lecture. The data are given in Table 6.23 and stored in QuizPulse10. We might expect mean pulse rates to increase under the stress of a quiz. Use the information in Exercise 6.250 and the data in Table 6.23 to test whether the data provide sufficient evidence to support this claim.
