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 0.24 ounces. A sample of 9 of these cheese wedges is selected. What is the mean and the standard deviation of the sampling distribution? 1. If a single wedge is selected, what is the probability its weight will be under 7.9 ounces? 2. If an SRS of 9 wedges is selected, what is the probability the mean weight will be under 7.9 ounces? 3. If a single wedge is selected, what is the probability, its weight will be between 7.9 and 8.02 ounces? 4. If an SRS of 9 wedges is selected, what is the probability, its weight will be between 7.9 and 8.2 ounces?
