1. The weight of frogs in grams in a marsh population are normally distributed with mean () equal to 23.5 grams and standard deviation () equal to 1.2 grams. What is the probability that a randomly sampled frog weighs less than 24 grams? Round your answer to four decimal places.

2. The weight of frogs in grams in a marsh population are normally distributed with mean () equal to 23.5 grams and standard deviation () equal to 1.2 gram. What is the probability that a randomly sampled frog weighs between 21 grams and 25 grams? Round your answer to fourdecimal places.

3. The weight of frogs in grams in a marsh population are normally distributed with mean () equal to 23.5 grams and standard deviation () equal to 1.2 grams. How much would a frog need to weigh (in grams) to be in the 85th percentile for weight? Round your answer to two decimal places.

4. Suppose the scores on a college entrance examination are normally distributed with a mean of 525 and a standard deviation of 110. A certain prestigious university will consider admission only for those applicants whose scores exceed the 95^th percentile of the distribution. Find the minimum score an applicant must achieve in order to receive consideration for admission to the university. Round your answer up to the nearest integer.

5. Suppose the scores on a college entrance examination are normally distributed with a mean of 525 and a standard deviation of 110. What score would place a student in the 35th percentile? Round your answer to the nearest integer.
