Foot lengths are approximately distributed with a mean of 24.2cm and standard deviation of 4.2cm. The percentage of people with a foot length between 20.0cm and 24.2cm is closest to:

• 16

• 32

• 34

• 52

• 68

The length of a type of ant is approximately normally distributed with a mean of 4.8mm and a standard deviation of 1.2mm. A standardised ant length of z=-0.5 corresponds to an actual ant length of:

• 2.4 mm

• 3.6 mm

• 4.2 mm

• 5.4 mm

• 7.0 mm

The shape of the histogram is best described as:

• Approximately symmetric

• Bell Shaped

• Positively skewed

• Negatively skewed

Parallel boxplots would be an appropriate graphical tool to investigate the association between the monthly median rainfall, in millimeters, and the:

• Monthly median wind speed in kilometres per hour.

• Monthly median temperature, in degrees Celsius

• Month of the year (January, February, March etc)

• Monthly sunshine time, in hours.

• Annual rainfall, in milimetres.

The median area of these islands, in square kilometres, is between:

• 2 and 3

• 3 and 4

• 10 and 100

• 1000 and 10 000

• 10 000 and 100 000

From the boxplots it can be concluded that the diameters of the jellyfish taken from location A are generally

• Similar to the diameters taken from location B

• Less than the diameters taken from B and less variable

• Less than the diameters taken from B and more variable

• Greater than the diameters taken from B and less variable

• Greater than the diameters taken from B and more variable

The median of this distribution is

• 1

• 2

• 3

• 4

• 5
