Melissa fipped her lucky coin 19 times and got 9 heads. Melissa used these numbers to estimate the probability of getting a head with her luoky coin. What is the estimated probability of Melissa fipping a head with her ludky coin? Number (Write your answer as a decimal rounded to 3 decimal places) Find the margin of error for Melissa's estimated probability above. Number (Write your answer as a decimal rounded to 3 decimal places) Create a confidence interval for the chance of fipping a head with Melissa's lucky coin. Number to Number (Write your answers as a decimal rounded to 3 decimal places) Can Melissa conclude that the probability of fipping a head with her lucky coin is actually different from 0.5? O Yes, the probability ofipping a head with Melissa's lucky coin was shown to be 0.474, which is clearly different from 0.5. Yes, the 95% confidence interval does not contain 50% so this shows evidence that the true probability of fipping a head for Melissa's lucky coin is 0.5. No, the 95% confidenoe interval contains 50% as a possibility so it would be illogical to think that Melissa's luoky coin has a probability different fro 0.5 based on her sample of data.
