Question 2
A manufacturer of Wi-Fi routers is investigating the maximum distance
(measured in meters) at which a signal can be detected at a certain
level for their product. Let D be the random variable of this maximum
distance. A frequency distribution of values of D was produced for a
random sample of 166 routers; it is shown in the table below. Setting
O; as the observed values and E, as the expected values for group i, the
last column shows calculated values of
