Please indicate the answer thank you! The average teacher's salary in Connecticut (ranked first among states) is $57,337. Suppose that the distribution ofsalaries is normal with a standard deviation of $7500.What is the probability that a randomly selected teachermakes less than $52,000 per year?The mean weight of 15-year-old males is 142 pounds, andthe standard deviation is 12.3 pounds. Find the probabilitythat 15-year old male will have a weight greater than 144.5pounds. Assume the variable is normally distributed.Based on your answer, would you consider the childoverweight?What is the probability that the next teacher's salary is lessthan $56,000?The average number of calories in a 1.5-ounce chocolatebar is 225.
