The shape of the distribution of the time required to get an oil change at a 15-minute oil-change facility is unknown. However, records indicate that the mean time is 16.1 minutes, and the standard deviation is 4 5 minutes Complete parts (a) through (c). (a) To compute probabilities regarding the sample mean using the normal model, what size sample would be required? O A. The sample size needs to be less than or equal to 30. O B. The sample size needs to be greater than or equal to 30. O C. The normal model cannot be used if the shape of the distribution is unknown. O D. Any sample size could be used.
