Over several years, students of Professor Robin Lock have flipped a large number of coins and recorded whether the flip landed heads ortails. As reported in a 2002 issue of Chance News, these students had observed 14686 heads in a total of 28870 flips What proportion of these flips resulted in heads? (Round answer to 2 decimal places, eg. 52.75%) % Use the Theory Based inference applet to calculate the standardized value of this statistic for testing whether the long run proportion of heads differs from 0.50. (Round answer to 2 decimal places, eg. 275.) Determine the theory-based p-value for testing whether the long-run proportion of heads differs from 0.50. (Round answers to 4 decimal places, es, 0.7523.)
What conclusion would you draw at the 0.05 significance level? Determine a 95% confidence interval for the long-run proportion of heads. (Round answers to 4 decimal places, es. 0.7523.) Confidence interval is to Does the confidence interval include the value 0.50? Based on the p value and conhdence interval, would you say that the difference between the sample proportion of heads and the value 0.50 is statistically significant? Would you say that the difference is practically important?
