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 sampled a group of 150 18-34 year olds, what is the probability that the number of them who checked their social media before getting out of bed is: a.) At least 30?  b.) No more than 54?  c.) between 36 and 49 (including 36 and 49)?  Use the Normal Approximation to the Binomial distribution to answer this question.
