Use the appropriate normal distribution to approximate the resulting binomial distributions. a convenience store owner claims that 55% of the people buying from her store, on a certain day of the week, buy coffee during their visit. a random sample of 35 customers is made. if the store owner's claim is correct, what is the probability that fewer than 24 customers in the sample buy coffee during their visit on that certain day of the week?
45.44/71 - 1 = -0.36 = -36%
you can make proportion:
38 : x = 2 : 309
when we multiply external and internal members we get.
2 x = 309 · 38 => x = 11742/2 = 5871 lbs
x = 5871 lbs
