1. To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades:
4.0 in a 5 credit Math course
2.1 in a 2 credit Music course
2.8 in a 5 credit Chemistry course
3.0 in a 4 credit Journalism course
What is the student's GPA for that term? Round to two decimal places. Student's GPA =

2.A set of exam scores is normally distributed with a mean = 80 and standard deviation = 6.
Use the Empirical Rule to complete the following sentences.

68% of the scores are between ____ and _____ .

95% of the scores are between _____ and _____ .

99.7% of the scores are between ______ and _______

3. To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades:

3.7 in a 5 credit Math course
2.4 in a 2 credit Music course
2.9 in a 4 credit Chemistry course
2.8 in a 4 credit Journalism course

What is the student's GPA for that term? Round to two decimal places.

1. The grade point average (GPA) of a large population of college students follows a normal distribution with mean 2.6, and standard deviation of 0.5. Students with GPA higher than 3.5 are considered “exceptional”, 3.0 to 3.5 are considered to be “good”, 2.0 to 3.0 are considered “average”, and below 2.0 are considered to be “poor”. (a) For a randomly selected student, what is the probability that he has a “good” GPA? 
 (b) Suppose 10 students are randomly selected. Let...
