A distribution of values is normal with a mean of 80 and a
standard deviation of 18. From this distribution, you are drawing
samples of size 12.
Find the interval containing the middle-most 88% of sample

Assume a binomial probability distribution has p = 0.80 and n = 400. (a) What are the mean and standard deviation?
Assume a binomial probability distribution has p = 0.80 and n = 400. (a) What are the mean and standard deviation? (Round your answers to two decimal places.) mean standard deviation (b) Is this situation one in which binomial probabilities can be approximated by the normal probability distribution? Explain. No, because np ≥ 5 and n(1 − p) ≥ 5. Yes, because np ≥ 5 and n(1 − p) ≥ 5. Yes, because np < 5 and n(1 − p)...
