The value of young's modulus (gpa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations.
115.8 116.5 116.1 115.5 114.8
(a) calculate x and the deviations from the mean.
(b) use the deviations calculated in part (a) to obtain the sample variance and the sample standard deviation. (enter your answers to three decimal places.)
c) calculate s2 by using the computational formula for the numerator sxx. (enter your answer to three decimal places.)
