In a dice game a pair of dice were thrown 180 times. The event "seven'" occurred on 38 of those times. If these dice are fair the probability of "seven"' is one-sixth. If they are loaded the probability is higher.
(a) is the probability of "seven" what it should be if the dice were fair? use a one-tailed test.
(b) find a 95% confidence interval for p ("seven") using the large sample approximation.

Suppose you’re playing a dice game in which two 6-sided dice are thrown, and players win when the sum of the values appearing on the dice is at least 7. In the last 100 games, you’ve noticed that players have won 95 times. Do you have any reason to believe that the dice are unfairly weighted using the central limit theorem? I have understood up to getting z=7.434. But how do you know to find P(z>7.434) and not use P(x<7.434)....

A gambler plays a dice game where a pair of fair dice are rolled one time and the sum is recorded. The gambler will continue to place $2 bets that the sum is 6, 7, 8, or 9 until she has won 7 of these bets. That is, each time the dice are rolled, she wins $2 if the sum is 6, 7, 8, or 9 and she loses $2 each time the sum is not 6, 7, 8, or...

Consider rolling a fair 6-sided dice. Which of the following statements are correct? Group of answer choices The probability that it lands on a 1 is 1/6. The probability of an even number on one roll of a dice is 2/6. The probability of an even number on one roll of a dice is 3/6. If we roll this dice a large number of times, then for about 5/6 of the time, it will NOT land on a 2. Suppose...

Twelve different video games showing substance use were observed and the duration of times of game play​ (in seconds) are listed below. The design of the study justifies the assumption that the sample can be treated as a simple random sample. Use the sample data to construct a 95​% confidence interval estimate of sigma​, the standard deviation of the duration times of game play. Assume that this sample was obtained from a population with a normal distribution. 4 comma 980...

Q1.Researchers were interested in determining the relative effectiveness of two different brands of eye drops in alleviating the symptoms of 'dry eye syndrome'. Forty subjects, who suffered from 'dry eye syndrome', were randomly assigned to receive either brand A or brand B of the eye-drops - 20 subjects to each brand. The eyedrops were administered to each subject and the time until symptoms returned was recorded for each subject. Based on the information provided, which of the following statement/s is...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
