a company campaign of a new product to the markets and expecting to sell it for $100. After the initial launch, they see that the price is too high and the manufacturing cost for the product is too high. So, if they decide that the price of the product needs to be $80 based on the cost of each sale. Then we randomly pick the cost of the sale in 10 randomly selected regions is $75. Then we determine the standard deviation of $10. How is a right-tailed hypothesis fits here?
