Suppose in a local Kindergarten through 12th grade (K - 12) school district, 53 percent of the population favor a charter school for grades K through five. A simple random sample of 500 is surveyed. Calculate the following using the normal approximation to the binomial distribution
(a) Find the probability that less than 200 favor a charter
school for grades K through 5.
(b) Find the probability that 260 or more favor a charter school
for grades K through 5.
(c) Find the probability that no more than 235 favor a charter
school for grades K through 5.
(d) Find the probability that there are fewer than 230 that favor a
charter school for grades K through 5.
(e) Find the probability that exactly 250 favor a charter school
for grades K through 5

1. In an August 2012 Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12. The bootstrap distribution (based on 5,000 samples) is provided. a). Would it be appropriate to use the normal distribution to construct the confidence interval in this situation? Explain briefly. b). The standard error from the bootstrap distribution is SE = 0.016. Use the normal distribution...
