There are about 45 more 2 year olds with a shoe size of 6 or less than 3 year olds with a shoe size of 6 or less.

The median of the two year old box plot, the bar in the middle, is at 6.  This means this is the halfway point of the data; half of the data will be above it, half below it.  There are 120 2-year-olds; 120/2 = 60.  This means there are 60 with that shoe size or smaller.

The lower quartile of the three year old box plot, the bar that makes the left side of the box, is at 6.5.  This is the middle of the lower half of data; 1/4 of the data is from this point below, and 3/4 of the data is from this point above.  There are 60 3-year-olds; 60/4 = 15.

The difference between the two is given by
60 - 15 = 45

A manufacturing company ships its product in two different sizes of truck trailers. Each shipment is made in a trailer with dime
kherson [118]

Answer:

Mean volume shipped per trailer load = 2960 ft³

Step-by-step explanation:

Since both trailers are always full,

Total volume in one 30 feet trailer shipment = 8 × 10 × 30 = 2400 ft³

Total volume in one 40 feet trailer shipment = 8 × 10 × 40 = 3200 ft³

Assuming a basis of 10 shipments, 3 shipments are done using the 2400 ft³ trailer and 7 shipments are done using the 3200 ft³ trailer.

Mean volume shipped per trailer load = total volume shipped/number of shipments

Total volume shipped = (3 × 2400) + (7 × 3200) = 7200 + 22400 = 29600 ft³

Number of shipment in the basis used = 10

Mean volume shipped per trailer load = 29600/10 = 2960 ft³
