Explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:
Given that:
P(x > 5.1 grams) = 5%, x = 5.1 grams, σ = 0.5 grams
P(x > 5.1 grams) = 5%
P(x < 5.1 grams) = 100% - 5% = 95%
P(x < 5.1) = 95%
From the normal distribution table, 95% corresponds with a z score of 1.645. Hence:
