1) A normal distribution has a mean of 50 and a standard deviation of 6. What is the probability that a value selected at random from this data is in the interval from 44 to 50?
2) A local bakery makes wheat bread. The number of grains of wheat in the bread is normally distributed, with a mean of 11.4g and a standard deviation of 1.3g. If this bakery sells 100 loaves of bread, approximately how many of the loaves (rounded to the nearest loaf) had less than 8.8g of wheat grains?
Please help me with these, I'm so stumped.
