Sample of 100 test specimen break tests of a steel alloy provides the following breaking strenths. Assuming thatthe breaking strength of samples in each range is actually at the minimum of the range, determine the meanbreaking strength and standard deviation of the sample. Using the same conservative assumption, determine thebreaking strength above which 95% of the sample values in the set are expected to fall.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
