The distance a basketball player runs during a game is one of the many variables used for assessing the performance of the players. 72 players are followed for each game and the average distance ran by them is found to be 3494 meters (m) with a standard deviation of 133m. Then the lower limit for the 95% confidence interval for the true mean and the upper limit is...

The distance a basketball player runs during a game is one of the many variables used for assessing the performance of the players. 78 players are followed for a game each and the average distance ran by them is found to be 3474 meters (m) with a standard deviation of 137 m. Then the lower limit for the 95% confidence interval for the true mean is Blank 1 and the upper limit is...

suppose a random sample of 50 basketball players have an average height of 78 inches. Also assume that the population standard deviation is 1.5 inches. I need to Calculate the 99% 95% 90% 80% and 70% confidence interval.
If the heights of male college basketball players and female basketball players are used to construct a 95% confidence interval for the difference between the two population means, the result is 15.35 cm < μ1 - μ2 < 19.81 cm, where heights of male players correspond to population 1 and heights of female players correspond to population 2. Express the confidence interval with heights of female basketball players being population 1 and heights of male basketball players being population 2. A) 15.25 cm < μ1 - μ2 < 19.81 cm B) -15.35 cm < μ1 - μ2 < -19.81 cm C) -19.81 cm < μ1 - μ2 < -15.35 cm D) This cannot be determined without having the original data values.
