A recent study has shown that 28% of 18-34 year olds check their Facebook/Instagram feeds before getting out of bed in the morning,

If we sample a group of 150 18- 34 year olds, what is the probability that the number of them to check their social media before getting out of bed is:

a.) at least 34?

b.) no more than 50?

c.) between 37 and 49 (including 37 and 49)?

Use the Normal Approximation to the Binomial distribution to answer this question.
