The wingspans of a common species of housefly are normally distributed with a mean of 0.5mm. Suppose that a biologist regularly collects random samples of 20 of these houseflies and calculates the sample mean wingspan from each sample. What will be the shape of the sampling distribution of the sample mean wingspan?
