The table below shows the choices made by 125 players on the first turn of a Rock-Paper-Scissors game. Recall that rock beatsscissors which beats paper which beats rock. A player gains an advantage in playing this game if there is evidence that the choicesmade on the first turn are not equally distributed among the three options. Use a goodness-of-fit test to see it there is evidence thatany of the proportions are different from=OptionFrequencySelectedRock66Раper43Scissors16Total125Table 1 Frequencies for first turn in Rock-Paper ScissorsPart 1Calculate the chi-square test statistic and the p-value.Round your answer for the chi-square statistic to two decimal places, and your answer for the p-value to three decimal places.p-value

Simulate observations having the binomial distribution with p = 0.25 and n = 1000. What is the probability of observing at least 240 A’s in such a sequence? [Hint: Obtain 10,000 simulations and compute the number of A’s in each run]. Compare your result with the normal approximation to binomial distribution.
Are Republicans more likely than Democrats to display the American flag in front of their residence on the Fourth of July? A simple random sample of 618 Republicans were surveyed and 408 said they display the flag on the Fourth of July. Another simple random sample of 615 Democrats were surveyed and 394 said they display the flag on the Fourth of July. Let p1p1 be the proportion of all Republicans who display the American flag on July 4th and p2p2 be the proportion of all Democrats who display the American flag on July 4th.

Assume that 900 births are randomly selected and 443 of the births are girls. Use subjective judgment to describe the number of girls as significantly high, significantly low, or neither significantly low nor significantly high.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Consider the following two datasets: A = { 5 , 23 , 8 , 12 , 4 , 21 } and B = { 20 , 10 , 16 , 1 , 18 , 8 , 4 } . select all correct options The sample medians of the datasets are equal. The sample means of the datasets are not equal The sample means of the datasets are equal. The ranges of the datasets are equal. The sample medians of the datasets are not equal.

A group of 100 BSSE girls from Riphah were selected to participate in a survey conducted by HEC to assess the satisfaction of students with online studies provided by the university. 48 % of the girls were high scorers while the rest were average scorers. 51 girls showed a lack of satisfaction with the studies including only 9 high scorers. Construct a 2 way cross tabulation and answer the following questions a. If a randomly selected student is an average score what is the probability that she would be satisfied with the studies b. What is the probability that a randomly picked student is a high scorer not satisfied with the studies c. What is the probability that a randomly picked students who is satisfied with the studies is a high-scorer girl
