The pulse rates of 176 randomly selected adult males vary from a low of 40 bpm to a high of 116 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 95% confidence that the sample mean is within 2 bpm of the population mean.
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 a game each and the average distance ran by them is found to be 3453 meters (m) with a standard deviation of 121 m. Then the lower limit for the 95% confidence interval for the true mean is ( Blank 1). Calculate the answer by read surrounding text. and the upper limit is ( Blank 2).

Nitrate concentrations above 50ppm in groundwater are not desirable for human consumption. Groundwater samples were taken from newly drilled boreholes in Northern Ghana for water quality analysis. The nitrate concentrations were as follows: 10, 87, 15, 29, 19, 109, 112, 45.5, 22, 99, 27, 88, 55, 5.5, 10.7, 9.7, 20.5. Determine at 99% level of confidence if groundwater in the area is of good quality.

According to a study, a cup of coffee contains an average of 118 milligrams (mg) of caffeine, with the amount poer cup ranging from 56 to 187 mg. Suppose you want to repeat the experiment in prder to obtain an estimate of the mean caffeine content in a cup of coffee correct to within 7 mg with 99% confidence. How many cups of coffee would have to be included in your sample? The experiment must sample cups of coffee in order to estimate the mean caffeine content in a cup of coffee correct to within 7 mg with 99% confidence. Round up to the nearest whole number.)
The Florida Department of Transportation (FDOT) would like to estimate the average speed of vehicles on 95. The mean speed , in miles per hour , of a random sample of vehicles was found to be 73 miles per hour. The standard deviation of the speeds of all vehicles on 1 - 95 is known to be 15 miles per hour . Find three different confidence intervals one with sample size 103, one with sample size 231, and one with sample size 370. Assume that the mean of each sample is 73 miles per hour . Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation . Round solutions to two decimal places, if necessary .
