The distribution of actual weights of 8-ounce wedges of cheddar cheese produced at a dairy is normal with mean 8.1 ounces and standard deviation 0.2 ounces. a sample of 10 of these cheese wedges is selected. the distribution of the sample mean of the weights of cheese wedges is:
approximately normal, mean 8.1, standard deviation 0.2.
approximately normal, mean 8.1, standard deviation 0.020.
it is not possible to tell because the sample size is too small.
approximately normal, mean 8.1, standard deviation 0.063.
