If you use NORM.INV(0.95, 100, 15), you are essentially asking:

Two statistics courses, Course A and Course B, have different instructors. The average score in Course A is 75 with a standard deviation of 10, while the average score in Course B is 80 with a standard deviation of 8. A student scores 85 in Course A and 84 in Course B. The z-scores for the student’s scores in each course are provide below. Determine which course the student performed relatively better in. Formula for Z-Score (z) = (X – μ) / σ Z-Score for Course A: (zA) = (85 – 75) / 10 = 1 Z-Score for Course B: (zB) = (84 – 80) / 8 = 0.5

What metric does total bill represent?  

During the first quarter of 2017, an investment group’s average purchase price of Bitcoin was $2,500.175 with a standard deviation of $600. The last purchase made was priced at $2,450.00. Assume that their purchase prices follow a normal distribution. To find the z-score for the last purchase, what value would be in place of x̄ when referring to the z-score formula below?
