Problem 5. For a binomial distribution with (i) n = 9, p = 0.7 find P(x < 6); (ii) n = 15, p = 0.6 find P(6 < x < 9); (iii) n = 1000, p = 0.003 find P(x = 3).
Consider a binomial distribution with n = 10 trials and the probability of success on a single trial p = 0.75. (a) Is the distribution skewed left, skewed right, or symmetric? (b) Compute the expected number of successes in 10 trials. (c) Given the high probability of success p on a single trial, would you expect P(r ≤ 2) to be very high or very low? Explain. (d) Given the high probability of success p on a single trial, would...

Compute P(X) using the binomial probability formula. Then determine whether the normal distribution can be used to estimate this probability. If so, approximate P(X) using the normal distribution and compare the result with the exact probability. 64, p 0.7, and X-40 For n-64, p = 0.7, and X-40, find P(X).
