Concept #1: Determining and Applying a Z-Score

Concept #2: Calculating and Applying a Z-Score: Intro

Practice: Assuming a data set is normally distributed with a mean of 100 and a standard deviation of 20, what is the z-score that represents a value of 120?

Practice: Referring to the data set in Practice 1, what is the z-score that represents a value of 110?

Practice: Referring to the data set in Practice 1, what is the z-score that represents a value of 119?

Practice: Assuming a data set is normally distributed with a mean of 100 and a standard deviation of 15, what is the z-score that represents a value of 119?

Practice: Referring to the data set in Practice 4, how and why is this z-score different from the z-score from Practice 3?

Practice: Referring to the data set in Practice 4, what is the probability of finding values between 115 and 130?
