Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Active Learning vs Passive Learning: Feelings of Learning? After the active learning or passive learning class, students rated the extent to which they agreed with the statement “I feel like I learned a great deal from this class.” Ratings were on a 5-point scale with greater numbers indicating greater agreement. For the 142 students in the active learning environment, the mean rating was 3.338 with a standard deviation of 0.922. For the 154 students in the passive learning lecture, the mean rating was 3.753 with a standard deviation of 0.873. Test whether ratings on feelings of learning are significantly lower, on average, with active learning. (Let Group 1 represent active learning and Group 2 represent passive learning.)
Cardiovascular Disease, Pulmonary Disease The duration of cigarette smoking has been linked to many diseases, including lung cancer and various forms of heart disease. Suppose we know that among men ages 30-34 who have ever smoked, the mean number of years they smoked is 12.7 with a standard deviation of 5.2 years. For women in this age group, the mean number of years they smoked is 9.4 with a standard deviation of 3.1. (Assume that number of years spent smoking can be measured exactly and no continuity correction is necessary. Round your answers to four decimal places.)
