Write a class named fan to model fans. the properties are speed, on, radius, and color. you need to provide the accessor methods for the properties, and the tostring method for returning a string consisting of all the string values of all the properties in this class. suppose the fan has three fixed speeds. use constants 1, 2, and 3 to denote slow, medium, and fast speeds.
the outline of the class is given as follows:
public class fan {
public final int slow = 1;
public final int medium = 2;

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
