Question

Technology is the key to our future. Apparently, students believe this also. According to an April 2009 poll of high school students by Ridgid, the top career choice for high school students was information technology, selected by 25% of the surveyed students. Suppose you randomly select 200 students from your local high school. Use the normal approximation to the binomial distribution to find the probability that within your sample:
a. more than 65 of the students picked information technology as their career choice.
b. fewer than 27 of the students picked information technology as their career choice.
c. between 45 and 60 of the students picked information technology as their career choice.
