A student constructs a small sailboat. A wind machine is able to blow air at a constant applied force of 5, 10, 15, or 20 newtons. The student places the boat in a large tank filled with water and tests each wind force setting on the machine.
Which wind force will result in the boat having the greatest speed?
5 nertons
10 newtons
15 neurons
20 newtons

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
