Laundry detergent use. The amount of laundry detergent that customers use has a right-skewed distribution with a mean of 30 milliliters (mL) and a standard deviation of 25 mL. Suppose we conducted a study in which we measured the laundry detergent use of 64 randomly sampled US adults. The corresponding sampling distribution of the sample mean, i.e.the distribution of all sample means based on all samples of size 64 from all US adults, has the folloing distribution O Normal O Approximately Normal O Not Normal
