There is a sample of 30 people and their shower times. What is the 95% confidence interval when sample mean is 23.50 minutes and standard deviation is 9.69 minutes?
The age when smokers first start from previous studies is normally distributed with a population standard deviation of 1.8 years old. 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 work
