1. The scores on a standardized test are normally distributed with a mean of 85 and standard deviation of 5. What test score is 1.1 standard deviations below the mean?
2. For a standard normal distribution, find: P(z < c) = 0.5748
3. For a standard normal distribution, find: P(0.66 < z < 1)
4. A particular fruit's weights are normally distributed, with a mean of 441 grams and a standard deviation of 13 grams. If you pick 23 fruit at random, what is the probability that their mean weight will be between 433 grams and 434 grams
