You work for a consumer watchdog publication and are testing the advertising claims of a tire manufacturer. The manufacturer claims that the life spans of the tires are normally distributed, with a mean of 40,000 miles and a standard deviation of 4000 miles. You test 16 tires and get the following life spans. Complete parts (a) through (c) below. 47,256 42,823 26,609 37,645 33,878 39,623 42,284 34,706 O 25,367 33,552 37,535 37,343 30,838 36,195 35,673 45,180 (a) Draw a frequency histogram to display these data.
