A large call center outside a city tracks the number of phone calls recieved each day. The daily number of phone calls recieved is normally distributed with μ=151and σ=6.8. Find the probability that on a randomly selected day the number of phone calls received is between 150 and 155. P(150 < X < 155) = Find the probability that a random sample of n=25 days has a mean number of phone calls recieved between 150 and 155. P(150 < M < 155) = Enter your answers as numbers accurate to 3 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted
