Answer: The mean of the frequency distribution is 51.7°.

The computed mean 51.7° is greater than the actual mean 50.7° .

Step-by-step explanation:

The given table :

Low Temperature (°F) Frequency Mid -value

Class interval f x fx

40-44 2 42.5 85

45-49 7 47.5 95

50-54 9 52.5 105

55-59 5 57.5 115

60-64 1 62.5 25

$\text{Now, Mean}=\dfrac{\sum fx}{\sum f}\\\\=\dfrac{85+332.5+472.5+287.5+62.5}{24}\\\\=\dfrac{1240}{24}=51.6666666667\approx51.7$

The computed mean 51.7° is greater than the actual mean 50.7° .
