Auniversity would like to estimate the proportion of fans who purchase concessions at the first basketball game of the season. the basketball facility has a capacity of 3 comma 600 and is routinely sold out. it was discovered that a total of 210 fans out of a random sample of 500 purchased concessions during the game. construct a 95% confidence interval to estimate the proportion of fans who purchased concessions during the game.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
