Afatigue test was conducted in which the mean stress was 70 mpa, and the stress amplitude was 210 mpa. (a) compute the maximum and minimum stress levels. (b) compute the stress ratio. (c) compute the magnitude of the stress range

This assignment is past the original due date o this data is from a sample. calculate the mean, standard deviation, and variance 16.7 11.1 46.7 14.8 13.3 16.6 18.5 47.3 42,8 show the following answers to 2 decimal places. sample mean- sample standard deviation ( use the standard deviation above for your calculation.) sample variance ooops- now you discover that the data was actually from a population! so now you must give the population standard deviation.
