Extracted text: 4 of 11 (5 completej This On Records taken from a hospital show that the times between arrving patients have a mean of 7.8 minutes with a standard deviation of 78 mintes. Besed solly on the valus of these two parameters, explain why it is unreasonable to assume that the times between arving patients is normaly distributed or even approximately so Select the correct choice below. O A. It is unreasonable because the standard deviation must be less than the mean for a variable to be normally distnbuted The given standard devatonsequal to he mean O B. It is unreasonable because the time between arriving patients cannot be less than O minutes and all the values between O and the mean le within teo standard deviatona O c. It is unreasonable because the time between arriving patients cannot be less than 0 minutes and all the values between O and the mean le within one standant deviation. OD. It is unreasonable because the standard deviation must be greater than the mean for a variable to be normaly distributed. The given standard deviation is equal to the mean
