The probability of any given baseball game going into extra innings (that is, lasting longer than nine innings) is 0.08 . You watch a total of 62 baseball games, keeping track of the number of games that go into extra innings. After watching all the games, you calculate widehat(p), the sample proportion of the 62 games that go into extra innings.
a. What is the probability that the sample proportion of 62 games that go into extra innings is greater than 0.07 ?
Answer:
Round to at least FIVE decimals if necessary
b. Suppose we are interested in an interval for widehat(p) such that P(a<=widehat(p)<=b)=0.85. What could the values a and b take? Assume we are creating a symmetric interval about the mean of the sampling distribution of widehat(p).
a= ◻ Round to at least FIVE decimals if necessary
b= ◻ Round to at least FIVE decimals if necessary
