A study of reliability of buses examined the reliability of 191 buses.

The distance travelled (in 1000s of miles)prior to the first major motor failure was classified into intervals. A modified form of the table follows.

DISTANCE TRAVELED(1000 MILES) |0-20.0 | 20.1-40.0 | 40.1-60.0 | 60.1-100.0

FREQUENCY |6 |11 |16 |59

DISTANCE TRAVELED(1000 MILES) |100.1-120.0 | 120.1-140.0 | 140.1-160.0 | 160.1-200.0
FREQUENCY |46 |33 |16 |4

A) Sketch the relative frequency histogram for the distance data and describe its shape.

B) Estimate the three most commonly used measures of central tendency for the distance travelled by the 191 buses.

C) What does the relationship among these measures of centre indicate about the shape of the histogram for these data?
