Complete parts (a) through (d) below. a. What proportion of trucks can be expected to travel between 47 and 60 thousand miles in a year? The proportion of trucks that can be expected to travel between 47 and 60 thousand miles in a year is 0.3814 (Round to four decimal places as needed.) b. What percentage of trucks can be expected to travel either less than 40 or more than 75 thousand miles in a year? 12.09 %. The percentage of trucks that can be expected to travel either less than 40 or more than 75 thousand miles in a year (Round to two decimal places as needed.) c. How many miles will be traveled by at least 99% of the trucks? The number of miles that will be traveled by at least 99% of the trucks is miles. (Round to the nearest mile as needed.)
