Some ofthe consequences of the drought was a sharp increase in hay prices, and the scarcity of hay.This impacted thousands of farmers and livestock owners across the country.In 2019, the price of teff hay increased to $32.00 for one bale. Bales of teff have an averageweight of 21kgs, which is assumed to be normally distributed, with a standard deviation of 1kg.Using the above information, answer the following questions, and make sure to explainyour answers by commenting on the choice and appropriateness of the test/methodology usedin your calculations: 1. Find the probability that if a horse owner buys one bale of teff hay, that bale will weightmore than 21.5kgs. (10 points) 2. Find the probability that if a horse owner buys 6 bales of teff hay, the mean weight of the6 bales is more than 21.5kgs. (10 points) 3. If a random sample of 25 bales had an average weight of 20.3kgs, what would you concludeabout the validity of the claim that the average weight of a bale of teff hay is 21kgs?
