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)...

a) What the mean and Standard Deviation (SD) of the Close column in your data set? b) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points) If a person bought 1 share...
