Start by choosing one of the first 5 states at the top of the list and record that state's name and data value below as the value for "State 1". Then, you will record every 3rd state's data after that until you reach 15 data values. INSERT TITLE OF DATA TABLE HERE (delete and replace with a title that describes what data is in the table) State 1 State 2 State 3 Data value 7.8 9.9 6.2 State 4 State 5 State 6 State 7 State 8 State 9 State 10 State 11 State 12 State 13 State 14 State 15 Name of state Arizona Colorado District of Columbia Hawaii Indiana Kentucky Maryland Minnesota Montana New Hampshire New York Ohio Pennsylvania South Dakota Utah 11.2 8.3 7.8 6 9.7 6 15.5 10.2 9.9 9.4 8.8 11.4 Analysis: Compute the mean and standard deviation of the sample data: Mean Standard deviation - Sample size = Page 1 of 3 410 words English (United States Focus -- + 12%

Answer 1

Sample size=15

$Mean=\frac{7.8+9.9+..+11.4}{15}=\frac{138.1}{15}=9.2066667$

$SD=\sqrt{\frac{7.8^2+9.9^2+..+11.4^2}{15}-(9.2066667)^2}$

1356.61 SD= (9.2066667)2 = 5.677954942 = 2.382845975 15
