Question

Question 3: (20 points) (A) The amount of tea leaves in a can from a particular production line is normally distributed with ? (mean) 132 grams and ? (Standard deviation) 12 grams. (i) What is the probability that a randomly selected can will contain less than 125 grams of tea leaves? (ii) If a sample of 16 cans is selected, what is the probability that the sample mean of the content "tea leaves" to be more than 135 grams? (B) In a city, it is estimated that the maximum temperature in July is normally distributed with a mean of 27° and a standard deviation of 4°. Calculate the probability of having a maximum temperature between 26° and 34°
