n a certain Algebra 2 class there is a total of 350 possible points. These points come from 5 homework assignments that are worth 10 pts. Each and 3 exams that are worth 100 pts. each. A student received homework grades of 4, 8, 7, 7 and 9 and the first two exam scores were 78 and 83
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

A student received homework grades of 4, 8, 7, 7 and 9 and the first two exam scores were 78 and 83. Is it possible for the student to receive an A in class and if so, what is the minimum score on the third exam that will give an A? What about a B?
