7) The breaking strength of nylon ropes made of two different materials (in hundreds of pounds) are shown below. Material 1: 487.3 444.5 467.7 456.3 449.7 459.2 478.9 461.5 477.2 488.5 501.2 475.3 467.2 462.5 Material 2: 499.7 470.0 469.5 481.5 485.2 509.3 479.3 498.3 Can conclude that the standard deviation of the breaking strength differs between the two you materials? Use the a = 0.05 level of significance. Show your work including how you get the test statistic and a graph showing the location of the test statistic and the critical value.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
