H0: p = 1/6
Ha: p > 1/6
Sample proportion
= 8/38 = 4/19
b)
Test statistic
z = (
- p ) / sqrt [ p( 1 - p) / n ]
= ( 4/38 - 1/6) / sqrt ( 1/6 * ( 1 - 1/6) / 38 )
= 0.73
p-value = P(Z > z)
= P(Z > 0.73)
= 0.2327
c)
Since p-value > 0.05 level, do not reject H0.
No. We fail to support the claim.

Pedro thinks that he has a special relationship with the number 2. In particular, Pedro thinks that he would roll a 2 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Pedro will roll a 2.(a) State the null and alternative hypotheses for testing Pedro's claim.

Problem 1. Suppose that you roll an 8-sided die until you get an 8. Let G denote the number of rolls that this takes. (a) Write down the probability mass function of G (b) Write a closed-form expression for P(G 2 6) (i.e. do not just write it as an infinite sum) (c) Do calculations to show that P(G2 10 | G> 6) P(G2 4).

1. Generating the sampling distribution of the mean Аа Аа Suppose you use sampling techniques to estimate the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8. To do this, you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample The true mean (u) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is and...
The Dice game of "Pig" can be played with the following rules. 1. Roll two six-sided dice. Add the face values together. 2. Choose whether to roll the dice again or pass the dice to your opponent. 3. If you pass, then you get to bank any points earned on your turn. Those points become permanent. If you roll again, then add your result to your previous score, but you run the risk of losing all points earned since your...
