According to national data, about 15% of American college students
earn a graduate degree. Using this estimate, what is the
probability that exactly 26 undergraduates in a random sample of
200 students will earn a college degree? Hint: Use the
normal approximation to the binomial distribution, where
p = 0.15
and
q = 0.85.
(Round your answer to four decimal places.)
I think this is the formula, Im having a hard time figuring out

According to national data, about 14% of American college
students earn a graduate degree. Using this estimate, what is the
probability that exactly 30 undergraduates in a random sample of
200 students will earn a college degree? Hint: Use the
normal approximation to the binomial distribution, where
p = 0.14
and
q = 0.86.

According to national data, about 10% of American college
students earn a graduate degree. Using this estimate, what is the
probability that exactly 23 undergraduates in a random sample of
200 students will earn a college degree? Hint: Use the normal
approximation to the binomial distribution, where p = 0.1 and q =
0.9. (Round your answer to four decimal places.)

According to national data, about 13% of American college
students earn a graduate degree. Using this estimate, what is the
probability that exactly 28 undergraduates in a random sample of
200 students will earn a college degree? Hint: Use the
normal approximation to the binomial distribution, where
p = 0.13
and
q = 0.87.
(Round your answer to four decimal places.)

. (10 pts.) According to the National Institute of Allergy and
Infectious Diseases, about 4.2% of American adults have a food
allergy. A large company plans a lunch reception for its 350
employees. Assume that employees are independent. Let the random
variable X be the number of company employees who have a food
allergy.
(a) What is the distribution of X?
(b) What are the mean and standard deviation of the distribution
of X?
(c) Using the Normal approximation (with...

2) Airline accidents: According to the U.S. National
Transportation Safety Board, the number of airline accidents by
year from 1983 to 2006 were 23, 16, 21, 24, 34, 30, 28, 24, 26, 18,
23, 23, 36, 37, 49, 50, 51, 56, 46, 41, 54, 30, 40, and 31.
a. For the sample data, compute the mean and its standard error
(from the standard deviation), and the median.
b. Using R, compute bootstrap estimates of the mean, median and
