A chocolate chip energy bar weights 70g, and the mean amount of protein in each bar is 8g. suppose the amount of protein in a bar is normally distributed with standard deviation = 0.15g

1. For one randomly selected that the amount of protein d energy bar, find the probability that the amount of protein is more than 7.75g
2. For a randomly sample of 9 energy bars, find the probability that the sample mean amount of energy is at lease 8.06g
