Goldilocks and Company manufactures wooden platform beds. The length of the wooden slats used to make a full-size bed must be between 74.8 inches and 75.2 inches to be declared "just right." Suppose that the length of the wood follows a normal random variable with mean 75 inches and standard deviation of 0.15 inch. To the nearest one-tenth of one percent, what is the percentage of wooden slats that are just right?

• 75.0%
• 81.8%
• 87.5%
• 90.9%
