Convenience Simple random sample is the

Frequency points

194. RF = relative frequency is

The relative frequency is equal to the frequency for an observed value of the data divided by the total number of data values
in the sample

195. 1; 11.5; 6; 7.2; 4; 8; 9; 10; 6.8; 8.3; 2; 2; 10; 1 Order from smallest to largest:

1;1;2;2;4;6;6.8;7.2;8;8.3;9;10;10;11.5

199. For the following 13 real estate prices, calculate the IQR . Prices are in dollars. 389,950; 230,500; 158,000; 479,000; 639,000; 114,950; 5,500,000; 387,000; 659,000; 529,000; 575,000; 488,800; 1,095,000

IQR = 649,000 – 308,750 = 340,250
