At a certain college in Louisiana, it is claimed that 77% of
the students at the college are receiving some form of student
tuition assistance. If 510 students at this college are randomly
selected, use the Normal approximation to binomial distribution to
find the probability that 370 or more of the students are receiving
some form of tuition assistance. (Hint: Remember to make the
continuity correction)

A researcher proposes to model daily coffee consumption among
college students by a normal distribution with mean 20 oz and a
standard deviation 4 oz.
What is the probability that a randomly selected student will
have coffee consumption in the range [mean-SD, mean+SD]?
2. Verify your answer by using R. Generate 1 million random
samples from the normal distribution with appropriate mean and
SD.
Does the normal distribution is in between[ 20-4, 20+4]?? For
the R code will that be...
