The distribution of actual weights of wedges of cheddar cheese produced at a dairy is normal with a mean of 11.3 ounces and a standard deviation of 0.19 ounces. (Round to 2 decimal places for all z-values and round all other answers to 4 decimal places, if needed.) The probability that the sample mean weight of this sample of 20 is less than 11.23 is .
