According to the N. Y. Times Almanac the mean family size in the U. S. is 3.18. A sample of a college math class resulted in the following family sizes:
5; 4; 5; 4; 4; 3; 6; 4; 3; 3; 5; 5; 6; 3; 3; 2; 7; 4; 5; 2; 2; 2; 3; 2
At α = 0.05 level, is the class’ mean family size greater than the national average? Does the Almanac result remain valid? Why?
