There is a popular lottery in which a ticket is called a scratcher. An ad for this lottery claims that the42%of the population all scratching posts are winners. You want to investigate this claim by selecting a random sample of48scratching posts Follow these steps to construct a confidence interval for the95%for the population proportion of all winning tickets. Then indicate whether the confidence interval you constructed contradicts the ad claim. (If necessary, you can refer to a list of formulas .) (to) Click on "Take sample" to see the results of the random sample. Take a sample Sample size: 48 winning scratching Point estimate: 0.25 post loser scratcher Number 12 36 Proportion 0.25 Enter the values for the sample size, the point estimate of the population proportion, and the critical value you need to construct the confidence interval of the95%. (Choose the correct critical value from the critical value table provided.) When finished, click on "Calculate". 0.75 Standard error: 0.063 Error range: X critical values 0.005=2,576 Ś
