A flywheel is retained on a shaft by five bolts, which are each tightened to a specific torque of 50(+ /- 5 ) Nm. A sample of 20 assemblies was checked for bolt torque. The results from the 100 bolts had a mean of 47.2Nm and a standard deviation of 1.38Nm. was identified. For these 20 bolts, the mean torque was 45.5Nm and the standard deviation 0.88 Nm. Assuming appropiate extreme-value distribution, calculate the probability that on a given assembly the lowest torque will be (i.) below 45NM; (b.) below 44Nm.

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
