solved:If np 2 5 and nq 2 5, estimate P(at least 7) with n = 13

  

If np 2 5 and nq 2 5, estimate P(at least 7) with n = 13 and p = 0.5 by using the normal distribution as an approximation to the binomial distribution; if np < 5 or nq < 5, then state that the normal approximation is not suitable. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. P(at least 7) = (Round to three decimal places as needed.) O B. The normal distribution cannot be used.... Show more MathStatistics and Probability STAT 2023
