Very confusing to me. A good explanation with answers would help. Thank you.

The distribution of actual weights of wedges of cheddar cheese produced at a dairy is normal with a mean of 8.0 ounces and a standard deviation of 0.19 ounces. [Round all answers to 4 decimal places. if needed.) (a) The probability that a randomly chosen wedge of cheddar cheese is greater than 7.94 is \\:l approximately normal approximately normal [b] If a sample of 20 is randomly chosen. then the distribution of the sample mean weight is [c] The probability that the sample mean weight of this sample of 20 is less than 7.94 is with a mean of not normal leftskewed rig hts kewed [d] The probability that the sample mean weight of this sample of 20 is greater than 7.94 is E. (e) The probability that the sample mean weight of this sample of 20 is between 7.94 and 8.11 is E. it] There is only a 2% chance that the average weight of a sample of these 20 cheese wedges will be below S
