If np 25 and nq 25, estimate P(fewer than 5) with n= 14 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(fewer than 5)=| (Round to four decimal places as needed.) O B. The normal approximation is not suitable.

The population mean and standard deviation are given below. Find the indicated probability and determine whether a sample mean in the given range below would be considered unusual. If convenient, use technology to find the probability. For a sample of n 38, find the probability of a sample mean being less than 12,750 or greater than 12,753 when u = 12,750 and o = 1.8. For the given sample, the probability of a sample mean being less than 12,750 or greater than 12,753 is. (Round to four decimal places as needed.) Would the given sample mean be considered unusual? O A. The sample mean would not be considered unusual because there is a probability greater than 0.05 of the sample mean being within this range. O B. The sample mean would be considered unusual because there is a probability greater than 0.05 of the sample mean being within this range. OC. The sample mean would not be considered unusual because there is a probability less than 0.05 of the sample mean being within this range. O…

Explain how to decide when a normal distribution can be used to approximate a binomial distribution. Choose the correct answver below O A. If np 0 and nq > 0, the normal distribution can be used. O C. If np 5 and nq 5, the normal distribution can be used. O D. If np 2 5 and nq 5, the normal distribution can be used. Click to select your answer.
