Question

Is that die fair? When playing a game with friends you notice that out of the past 15 rolls 5 resulted in the number 4. This seems like a lot to you and so you want to test whether the die is weighted to give more fours than a fair six-sided die would ordinarily give. Question 2 (1 point) What value should we use for the null hypothesis? Ho: π 1/6 Oo 5/15 Question 3 (1 point) Saved Which mathematical symbol would you use for the alternative hypothesis?

    When playing a board game, you notice that you seem to be rolling a lot of 6’s. Suspecting that the die may be loaded (in a way that favors rolling a 6), you give the die 50 test rolls. The die came up “6” a total of 15 times. (4 pts) State a null hypothesis and alternative hypothesis (symbolically) to test the claim that the die is loaded (as you suspect it is).

    15. Your friend challenges you to a game. She says that she is going to roll 2 6-sided dice. If the first die rolls at least 5, you win if the second die rolls less than 5. If the first die rolls less than 5, you win if the second die rolls at least 5. This seems fair. Is it? (a) What is the probability that you win this game? To incentivize you, your friend says that she will pay...

    Jorge was at the park playing with friends. He found a typical die with 6 sides on the ground. He took it home and rolled it 100 times and recorded the results (found in the table below). He wanted to see if the die was a 'fair die' or if it was weighted on one side so somone could cheat when playing games! Is this a 'fair die' or has it been tampered with? Test at the α=0.10α=0.10 level of...

    1. I have a six sided die. My suspicion is that the die is not fair, rather it is weighted to rol twos more often then expected with a fair die. To investigate this I roll the die 100 times. In those 100 rolls, I observe 21 twos.

    In a dice game, you roll a fair die three times, independently. If you don’t roll any sixes, you lose 1 dollar. If you roll a six exactly once, you win one dollar. If you roll a six exactly twice, you win two dollars. If you roll a six all three times, you win k dollars. (A) Let k = 3. What is the expected value of the amount you would win by playing this game (rounded to the nearest...

    3. In this question we simulate the rolling of a die. To do this we use the func- tion runif (1),which returns a randomnumber in the range (0,1). To get a random integer in the range (1,2,3,4,5,6), we use ceiling(6 runif (1)) or if you prefer, sarple(1:6,size-1) will do the same job. (a). Suppose that you are playing the gambling game of the Chevalier de Méré. That is, you are betting that you get at least one six in 4...
