Question

Evaluating probability: A particular type of frog's weights are normally distributed, with a mean of 609 grams and a standard deviation of 25 grams. If you pick one frog at random, find the following: (round all probabilities to four decimal places)

a) What is the probability that the frog weighs less than 563 grams?

b) What is the probability that the frog weighs more than 695 grams?

c) What is the probability that the frog weighs between 563 and 695 grams?

d) Is it unlikely that a randomly chosen frog would weigh less than 563 grams?

No, the likelihood exceeds 50%

No, the likelihood exceeds 5% Yes, the likelihood is less than 5%

Yes, the likelihood is less than 50%

e) What is the cutoff for the heaviest 10% of this type of frog? (round to the nearest whole gram)
