2.In Dungeons and Dragons, a 20-sided die is often used in place of the standard 6sided die. A roll above a 10 (i.e., 11-20) is usually considered a “good" roll. The Masked Royalethinks he's unlucky in this department. To test this theory, he rolls a 20-sided die 161 timeswhile playing. 74 rolls are above a 10.a)Create a 95% confidence interval for the true proportion of times The MaskedRoyale rolls above a 10. Use this interval to determine whether the Masked Royale is trulyunlucky or not.b)The Masked Royale decides to resample and create a new 95% confidence interval.Determine the sample size needed to keep the margin of error for the Masked Royale's intervalat 0.01. You can use the previous sample's proportion in your calculations.
