The following figure is a probability density curve that represents the grade point averages (GPA) of the graduating seniors at a large university. Area = 0.64 Area = 0.23 3.3 3.7 4.1 4.5 4.9 Part 1 of 2 Find the proportion of seniors whose GPA is between 4.1 and 4.5. The proportion of seniors whose GPA is between 4.1 and 4.5 is X 5 Part 2 of 2 What is the probability that a randomly chosen senior will have a GPA greater than 4.5? The probability that a randomly chosen senior will have a GPA greater than 4.5 is X 5Use the TI-84 Plus calculator to find the :-scores that bound the middle 80% of the area under the standard normal curve. Enter the answers in ascending order and round to two decimal places. The :-scores for the given area are l and l _ ' X S A normal population has mean it : 9 and standard deviation 6 : 5. (a) What proportion of the population is less than 19? (b) What is the probability that a randomly chosen value will be greater than 4? Round the answers to four decimal places. Part 1 of2 The proportion of the population less than 19 is Part2 on The probability that a randomly chosen value will be greater than 4 is
