Solve the forwards problem below. Round all z-scores to the nearest hundredth when necessary. A survey among freshmen at a certain university revealed that the number of hours spent studying the week before final exams was normally distributed with a mean of 25 hours and a standard deviation of 7 hours. Determine the probability that a freshman studied for between 20 and 24 hours. smaller z-score: Work: larger z-score: Work: Which image below (A, B, C, or D) looks most similar to the curve you drew?

Solve the forwards problem below. Round all z-scores to the nearest hundredth when necessary. Lena finds that a sample of children first begin to comine words at x = 20.7 months with a standard deviation of s = 1.95 months. If the distribution is approximately normal, what is the probability that a child will begin to combine words after x = 18 months? Z-Score: Work: Which image below (A, B, C, or D) looks most similar to the curve you drew? A Area from the Table: Final Answer: Work:
