STAT 121 LAB 7 4 Say I told you that the true value of p was p = 0.85

QUESTION

Please do this on R studio presentation and type in the code you need for the presentation as well as the explanation for the questions that need it. email the code use for the r presentation to n..z@mynbps.org with explanation pleaseRead in the proptest_data2.csv data set provided on connect. The dataset contains 10 draws of flipping a coin 20 times. Each of these is stored as a column with 1 indicating a success and 0 a fail. Calculate the 95% confidence interval of the proportion of successes using pˆ ± 2se(pˆ).Say I told you that the true value of p was p = 0.25. How many of the 95% confidence intervals contain the true value of p?Using your answer from question 2, what would you estimate the level of confidence of your confidence intervals to be?Does this match the true level? (The level that you used to calculate them in the first place).Use prop.test() to calculate 95% CI’s for the first 4 columns of proptest_data2.csv.Which method is better?Read in the proptest_data3.csv data set provided on connect.
