The number of birth defects in a region is commonly modeled as having a binomial distribution, with a rate of four birth defects per 100 births considered a typical rate in the United States. What is the probability that a county that had 200 births during the year would have between 4 and 12 birth defects. Use both the binomial distribution and the Normal approximation with the appropriate continuity correction from the table below. Is the normal approximation reasonable?

The number of birth defects in a region is commonly modeled as having a binomial distribution, with a rate of four birth defects per 100 births considered a typical rate in the United States. What is the probability that a county that had 200 births during the year would have between 4 and 12 birth defects. Use both the binomial distribution and the Normal approximation with the appropriate continuity correction from the table below. Is the normal approximation reasonable?
Binomial Distribution
P(x = 10)
P(x > 10)
P(x <= 10)
P(x = c)
P(x > c)
P(x <= c)
P(x<c)
P(x >= c)
P(a<x< b)
P(x < 10)
P(x >= 10)
P(9<x<11)
Normal Approximation
P(9.5<x< 10.5)
P(x > 10.5)
P(x < 10.5)
P(c-0.5<x<c+0.5)
P(x > c +0.5)
P(x<c+0.5)
P(x<c-0.5)
P(x < 9.5)
P(x > c-0.5)
P(x > 9.5)
P(a -0.5 < x < b +0.5) P(8.5<x< 11.5)
