TEAM PROJECT. Difficulty with Random Selection. 77 students were asked to choose 3 of
Chapter 25, Problem 25.1.115(choose chapter or problem)
Difficulty with Random Selection. 77 students were asked to choose 3 of the integers 11,12,13, \(\cdots, 30\) completely arbitrarily. The amazing result was as follows.
If the selection were completely random, the following hypotheses should be true.
(a) The 20 numbers are equally likely.
(b) The 10 even numbers together are as likely as the 10 odd numbers together.
(c) The 6 prime numbers together have probability 0.3 and the 14 other numbers together have probability 0.7. Test these hypotheses. using \(\alpha=5 \%\). Design further experiments that illustrate the difficulties of random selection.
