ONE STEP FURTHER: Data was collected from 252 students on the number of hours they slept the previous night. The 95% condence interval created by Iinnitab was: {7.34, 7.71). 1. For each of the following statements determine if they are correct or incorrect interpretations of this interval, assuming these students represent a simple random sample of all students in the class. Do this rst by yourself, then compare and discuss with your partner and your table. C 7' I a. 95% of students slept between 7.34 and 7.71 hours the previous night. C I I b. We are 95% condent that the average number of hours those 252 students in the sample slept the previous night is between 7.34 and 7.71. C I I c. We are 95% condent that the average number of hours all students in the class slept the previous night is between 7.34 and 7.71. C .u' I d. The probability that the population mean is included in a 95% condence interval is 0.95. C I I e. The probability that the population mean is between 7.34 and 7.71 is 0.95
