A random sample of 18 college men's basketball games during the last season had an average atendance of 5,199 with a sample standard deviation of 1,700. Complete parts a and b below a. Construct a 95% confidence interval to estimate the average attendance of a college men's basketball game during the last season The 95% confidence interval to estimate the average attendance of a college men's basketball game during the last season is from a lower limit of to an upper limit of (Round to the nearest whole numbers.) b. What assumptions need to be made about this population? OA. The only assumption needed is that the population distribution is skewed to one side OB The only assumption needed is that the population follows the Student's t-distribution OC. The only assumption needed is that the population size is larger than 30 OD. The only assumption needed is that the population follows the normal distribution A random sample of 18 college men's basketbal games during the last season had an average attendance of 5,199 with a sample standard deviation of 1.700.
