A survey of smokers of this generation was done to estimate the mean age. The sample of 35 smokers found that their mean starting age was 14.7 years old. Find the 95% confidence interval of the mean. Also, draw and label the distribution to support your workA laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with s = 17.6 milligrams. Assuming the population has a normal distribution, construct a 95% confidence interval for the true mean cholesterol content of all such eggs. You may compute this by hand or use technology. << (Round your final answer to 1 decimal)

- 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 3494 meters (m) with a standard deviation of 133 m. Then the lower limit for the 95% confidence interval for the true mean is and the upper limit is ious NEXT SaveA musicologist is currently writing a report about pop songs in the late 2010s. As a part of his research, the musicologist would like to estimate the mean length of pop songs in the late 2010s. A random sample of 155 pop songs from the 2010s was selected and the average of the sample was found to be 3.01 minutes. Suppose the standard deviation of the lengths of all pop songs in the late 2010s is known to be 0.3 minutes Find three different confidence intervals one with a 99% confidence level, one with a 97% confidence level, and one with a 90% confidence level for the average length of all pop songs in the late 2010s. Notice how the confidence level affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Round solutions to three decimal places, if necessary The margin of error for a 99 confidence interval is given by E = A 99% confidence interval is given by The margin of error for a 97 confidence interval is given by E…Please help!!
