Suppose a Montana cattle rancher has steers that in prior years had an average live weight of 380 pounds. Suppose that this year the Montana rancher changed the feed for the steers resulting in a new diet. The number of steers this year that survived to slaughter numbered 50 with an average weight of 390 and a standard deviation of 35.2. Assuming large sample size, the Montana cattle rancher wishes to use the normal distribution at o = .01 to determine if the mean weight of the Montana rancher's steers is greater than in prior years. Determine the p-value. O 0.02227779 O .017422665 O .005258255 O.025659444 O none of the other answer choices
