2) Give the mean monthly temperature of July using the chart .

Answer 1

(a) Mean yearly temperature = 10.58

(b)
`July = 24^\circ C`

Step-by-step explanation:

Given:

The attached chart

Solving (a): The mean yearly temperature.

This is calculated as:

`\bar x = (\sum x)/(n)`

`\bar x = (-5 + 2 + 6 + 10+15 + 22+24+21+17+12+6-3)/(12)`

`\bar x = (127)/(12)`

`\bar x = 10.58`

Solving (b): The mean July temperature.

From the chart:

`July = 24^\circ C`
