Suppose that the average number of equipment breakdowns at a
factory per week is 5. Later we’ll show that the average is our
best guess at the expected value of ? = ?ℎ? ?????? ?? ?????????
?????????? ?? ? ????? ???? (assuming that this distribution stays
the same across multiple weeks.) It’s also known that, through some
other sample statistic, that our best guess at the standard
deviation of X given the data is 0.8. a. With the help of...
