The distribution of the time that it takes a group of mechanics to do an oil change at a garage shop is unknown. However, it takes the mechanics an average of μ = 20 minutes to do an oil change with a standard deviation of σ = 2 minutes. A manager at this shop draws a sample of 36 oil changes to monitor the mechanics' efficiency. Let X represent the sample mean time for these 36 oil changes. Select all that apply.
