A new nickel alloy is being tested, and here is the distribution of the test data, is tech yield strength normally distributed at the 5% signification level? Use visual test, with histogram. Use test (chi-square) (do both and you will each the higher score of tech two)

Solution

we know that the yield stress is directly related(proportional ) to the observed frequency

when compared to other complicated observations in the given test data the yield strength is normally distributed over frequency

this observation is made by seeing the data given .as it linearly varying we can say that it is normally distributed.
