A tire company has developed a new steel-belted radial tire. Intensive testing indicates dilation of mileages obtained by all tires of this new type is normally distributed with a mean of 36,483 miles and a standard deviation of 3,734 miles. The company wishes to offer a guarantee providing a discount on a new set of tires if the original tires purchased Do not exceed the mileage stated in the guarantee. What should the guaranteed mileage be if the company desires at no more than 2 percent of the tires will fall to meet the guaranteed mileage?

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
