1. Suppose we have a loaded die which gives the outcomes 1 through 6 according to the probability distribution
Note that for this die all outcomes are not equally likely as they would be if this were a fair die. If this die is rolled 6000 times, then , the sample mean of the number of spots on the 6000 rolls, should be about
A. 3.00.B. 3.30.C. 3.50.
2. Suppose we have a loaded die which gives the outcomes 1 through 6 according to the following probability distribution.
Note that for this die all outcomes are not equally likely as they would be if this were a fair die. If this die is rolled 6000 times, the number of times we get a 2 or a 3 should be about
A. 1000.B. 2000.C. 3000.
