Answer:
(a) Mean yearly temperature = 10.58
(b) [tex]July = 24^\circ C[/tex]
Explanation:
Given:
The attached chart
Solving (a): The mean yearly temperature.
This is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{-5 + 2 + 6 + 10+15 + 22+24+21+17+12+6-3}{12}[/tex]
[tex]\bar x = \frac{127}{12}[/tex]
[tex]\bar x = 10.58[/tex]
Solving (b): The mean July temperature.
From the chart:
[tex]July = 24^\circ C[/tex]
