s 1-4 regarding standard deviation/probability. 1.) According to the label, a can of soup holds an average of 303 grams, with a standard deviation of 4.3 grams. Assuming a normal distribution, what is the probability that a can will be sold that holds more than 304 grams? Round answer to 4 decimal places. 2.) A jar of peanut butter contains 454 grams with a standard deviation of 10.2 grams. Assuming a normal distribution, find the probability that a jar contains less than 451 grams. Round answer to 4 decimal places. 3.) Assume that the distribution of starting salaries for accounting majors is normally distributed woth mean $45,000 and standard deviation $3,200. What is the probability that an individual will start at a salary above $52,000? Round answer to 4 decimal places. 4.) Suppose that the life expectancy of a certain brand of no defective light bulbs is normally distributed, with a mean life of 1300 hours and a standard deviation of 100 hours. Find the probability that a light bulb of this brand selected at random lasts less than 1110 hours, using the normal distribution as a model. Put answer as an integer or decimal
