Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to flip the coin in order to obtain a 96.5% confidence interval of width of at most .12 for the probability of flipping a head? (note that the z-score was rounded to three decimal places in the calculation) a) 309 b) 226 c) 229 d) 312 e) 306 f) None of the above

Imagine an experiment where we flip a coin 6 times, and get “head, tail, head, head, head, head”. Which of the following statements are true? a) The coin is not fair b) The coin’s tail probability is 1/6 c) The sequence "head, tail, head, head, head, head" is an outcome in the sample space. d) The sample space of the experiment is {head, tail}

Suppose you want to test how fair is the coin. You conduct the following experiment. You flip the 2 coins multiple times and observe HH - 14 times, HT - 18 times, TH - 13 times, and TT - 34 times. What is the Test Statistics to test the Null Hypothesis that the coin is fair against the alternative hypothesis that the coin is unfair?

Using R-studio 2. Consider an experiment where we flip a fair coin six times in a row, and i is the number of heads tossed: a. Calculate the probability mass function for i = 0. . . 6 using the equation from Ross section 2.8 for Binomial Random Variables b. Conduct a simulation of this experiment in R, with T trials of the experiment – pick several values of T from 10 to 10,000. c. Create a plot of the...
