The sample size n, probability of success p, and probability of failure q are given for a binomial experiment. Decide whether you can use the normal distribution to approximate the random variable x. n=17 p=0.26 q=0.74 Can the normal distribution be used to approximate the random variable x? O A. No, because np <5 and ng <5. O B. No, because nq <5. OC. Yes, because np25 and nq 25. O D. No, because np <5.

Let X be a normal random variable with mean 48 and standard deviation 3.8. Suppose that x = a has a z-score of z = 2.5. How do we interpret this z-score? Group of answer choices: x = a has a difference of 2.5 with x = 48 x=a is 2.5 standard units away from x = 48. x = a is 3.8 standard units away from x = 48 x = a is has a difference of 3.8 from x = 48.

Renee and Thomas live at the beach and collect seashells. The number of shells Renee collects on any given day, R, is approximately Normal with a mean of 58.2 shells and a standard deviation of 12.8 shells. The number of shells Thomas collects on any given day, T, is approximately Normal with a mean of 47.9 shells and a standard deviation of 11.5 shells. Assume the two random variables are independent of each other. What is the probability that on a randomly selected day the total number of shells collected by Renee and Thomas is 120 or more? 0.002 0.209 0.284 0.791
