tread life of its snow tires can be described by a Normal model with a mean of 32,000 miles and a standard deviation of 2500 miles. Complete parts a through e below. a) If you buy a set of these tires, would it be reasonable for you to hope that they'll last 40,000 miles? Explain. About % of tires are expected to have a tread life greater than 40,000 miles. It be reasonable to hope that your tires lasted this long. (Round to one decimal place as needed.) b) Approximately what fraction of these tires can be expected to last less than 28,000 miles? About % of these tires can be expected to last less than 28,000 miles. (Round to one decimal place as needed.) c) Approximately what fraction of these tires can be expected to last between 28,000 and 35,000 miles? About % of these tires can be expected to last between 28,000 and 35,000 miles. (Round to one decimal place as needed.) d) Estimate the interquartile range (IQR) for these data. The IQR is miles. ( Round to the nearest mile as needed. ) Time Remaining: 02:23:56 Next Textbook Statcrunch 99+ ENG 9:34 PM US 2022-07-02
