Given a population in which the probability of success is .25. if a sample of 200 items is taken. then complete parts a and b. a. Calculate the probability the proportion of successes in the sample will be between 0.22 and 0.30. b. Calculate the probability the proportion of successes in the sample will be between 0.22 and 0.30 if the sample size is 100.

a. The probability the proportion of successes in the sample will be between 0.22 and 0.30 is . (Round to four decimal places as needed.)

b. The probability the proportion of successes in the sample will be between 0.22 and 0.30 if the sample size is 100 is . (Round to four decimal places as needed.)
