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
The computed mean 51.7° is greater than the actual mean 50.7° .
In the table y is increased 70 for every 1 in x
(210/3 = 70)
on the graph for every 1 increase on x y increases by 55
(110/2 = 55)
so for the graph for x = 11, y =55 x 11 = 605
for the table for x = 11, y = 11*70 = 770
the difference is 770-605 = 165
the 2nd answer is the correct one.
-17 is smaller than -6. think about it this way: Would you rather have -6 or -17 on your test? The less wrong the better score you have. When it comes to negatives, the bigger number is always smaller.
