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
The mean distance commuted by a sample of 100 people is 25 miles. If the standard deviation of the distance commuted by the population of all commuters is known to be 3 miles, find the confidence interval for mean distance commuted by the population of all commuters for a confidence level of 95%
The annual per capita consumption of oranges (in pounds) in the United States can be approximated by a normal distribution.

A veterinarian wants to estimate the mean weight of a cat in their city. They take a random sample of 19 cats and found a mean of 10.9 lbs with a sample standard deviation of 1 lbs. Find the 95% confidence interval of the mean. Assume that the cat weights are normally distributed. Do not round in between steps. Round answers to at least 4 decimal places. < Select an answer <
Assume that adults have IQ scores that are normally distributed with a mean of mu = 100 and a standard deviation sigma = 20. Find the probability that a randomly selected adult has an IQ between 84 and 116 and type an integer or decimal rounded to four decimal places. Make sure to use the positive or negative z score charts attached, in the eBook on MSL, or in a hardcopy of the textbook.

Assume that the square footage of a residential house in the US is normally distributed with a mean=1000 and standard deviation=150 square feet. Suppose we select 450 houses from a town and we find that the mean of those houses is 1230 square feet (the standard deviation remains the same). What is the 95% confidence interval for this sample? from 1216 to 1244 from 1250 to 1320 from 1126 to 1294 from 1038 to 1420
