1. A class is given an exam. The distribution of the scores is normal. The mean score is 70 and the standard deviation is 11. Determine the test score, cc, such that the probability of a student having a score greater than cc is 61%61%. P(x>c)=0.61P(x>c)=0.61 Find c rounded to one decimal place. 2. A particular fruit's weights are normally distributed, with a mean of 726 grams and a standard deviation of 26 grams. If you pick one fruit at random, what is the probability that it will weigh between 742 grams and 791 grams

Question

1. A class is given an exam. The distribution of the scores is normal. The mean score is 70 and the standard deviation is 11. Determine the test score, cc, such that the probability of a student having a score greater than cc is 61%61%.

P(x>c)=0.61P(x>c)=0.61

Find c rounded to one decimal place.

2. A particular fruit's weights are normally distributed, with a mean of 726 grams and a standard deviation of 26 grams.

If you pick one fruit at random, what is the probability that it will weigh between 742 grams and 791 grams
