Sol:
mean=1539.6
median=1503
mean>median
distribution is positively skewed(more data are on the left
There are outliers seen from the histogram.
As it is skewed disribution center is median as it is not affected by outliers.
center:1503:
spread is standard deviation=530.8854

A)The data were collected in a study conducted in a semiconductor manufacturing plant. In this plant the finished semiconductor is wire bonded to a frame. The goal of the study was to relate a pull strength to a wire length and a die height. The variables obtained for each subject were a pull strength (a measure of the amount of force required to break a bond), a wire length, and a height of a die. What is the type of...
