In a destructive test of product quality, a briefcase manufacturer places each of a simple random sample of the day’s production in a viselike device and measures how many pounds it takes to crush the case. from past experience, the standard deviation has been found to be 21.5pounds. for 35 cases randomly selected from today’s production, the average breaking strength was 341.0 pounds. the lower confidence limit of 99% confidence interval for the mean breaking strength of the briefcases produced today would equal to;

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
