The average final exam score for the statistics course is 74%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is lower. The final exam scores for the 11 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 76, 78, 77, 67, 63, 79, 50, 63, 70, 63, 66 What can be concluded at the the a = 0.01 level of significance level of significance? a.

A bottling company fills bottles with water you measure the liquid volume of 6 bottles and get: 745, 751, 748, 747, 750,744 ml.a/ Describe the volumes of this set of bottle with only two numbers. b/ if this were a set of 6 out of several thousand calculate the average volume. C/ The company is trying to fill each bottle to 750 ml but there's some random variation in the machine and there might be some evaporation. Is evaporation likely given these numbers?
1. Of all freshman at a Snow college, 16% made the dean's list in the current year. As part of a class project, students randomly sample 40 freshman and check if those students made the list. Calculate the probability your sample has more than 8 students from the dean's list. Check conditions (if one doesn't check out, note your concern and continue anyway), describe sampling distribution, state probability.
