Question

The histogram represents the distributions of boiling

Answer 1

Answer:

The mean boiling temperature of the tap water is 2°C less than hat of the mixture of salt water.

Step-by-step explanation:

The complete question is attached below.

From the provided data it can be seen that the distributions of boiling  temperatures, in degrees Celsius, of both tap water and a  mixture of salt water are approximately symmetric.

It is known that, for a symmetric distribution,

Mean = Median = Mode

The median for the two distributions are:

Median (Tap water) = 100°C

Median (Mixture of salt water) = 102°C

Then the mean for the two distributions would be:

Mean (Tap water) = 100°C

Mean (Mixture of salt water) = 102°C

So, the mean boiling temperature of the tap water is 2°C less than hat of the mixture of salt water.
