If I wanted to further test the assumption that 78% of Freedom Academy students love to dance to 80s music, what would be the minimum sample size for the 95% confidence interval to be accurate within 6%? Need help fast now, thanks.

Step 1
96) p = estimated proportion (assumed to be 0.78 in this case) E = margin of error (assumed to be 0.06 in this case) Plugging in the values, we get: n = (1.96^2 * 0.78 * (1-0.78)) / 0.06^2 Simplifying the equation: n = (3.8416 * 0.78 * 0.22) / 0.0036 n = Show more…

A random sample of 72 statistics students was taken to estimate the proportion of students who also were in the Math Club. The 90% confidence interval was 0.438 to 0.642. Using this information, what size sample would be necessary to estimate the true proportion to within a margin of error of 0.08 using 95% confidence?
