d) Which of the following is a correct interpretation of the 95% confidence level?i) There is a 95% probability that the mean breaking strength is in your interval.ii) In about 95% of all samples for which this procedure is used, the confidence interval willcover the true population mean, but there is no way to know if this interval covers thetrue mean or not.iii) If this test was to be repeated with a sample of the same size, there is a 95% probabilitythat the sample mean would be in your interval.iv) 95% of the time the breaking strength of the wire are in your interval.e) How do your results in c) support your findings in b) and based on your results, which barb-wiredo you think is better. Two types of wire, a 12 ½-gauge low-carbon wire and a thinner 14-gauge high-tensile wire,both used in barbed-wire fencing, are tested to see which wire is stronger. A sample of 20wires of each gauge was taken and the breaking strengths, in pounds, of both types of wire wasdetermined. [The gauge is a number that refers to the thickness of the wire. The higher thenumber the thinner the wire.]The results are given below.12 ½-gauge, low-carbon wire:MinimumLowerMedianUpperMaximumquartilequartile730765782.580582514-gauge, high-tensile wire: (Individual measurements)780780775770780780790780770780780785800775760770800780790790a) For the 14-gauge wire, determine the 5-number summary of the tensile strength.b) Compare the Centre and Spread of the 2 sets of data, using the 5-number summaries for the12.5-gauge and 14-gauge wire.
