Verified Answer
The mid-value of a class interval is 42. If the class size is 10, then...
Let the lower limit of a class = x
class size = 10
Upper limit = x + 10
Now, mid - value =
= x + 5 = 42 (given)
x = 37 = lower limit
x + 10 = 47 = upper limit
pper and lower limits are 47, 37
class size = 10
Upper limit = x + 10
Now, mid - value =
= x + 5 = 42 (given)x = 37 = lower limit
x + 10 = 47 = upper limit
pper and lower limits are 47, 37

The mid-value of a class interval is 42. If the class size is 10, then...
Explanation:
To find the upper and lower limits of a class interval, we need to know the mid-value and the class size.
Given:
Mid-value = 42
Class size = 10
Calculating the lower limit:
The lower limit is found by subtracting half of the class size from the mid-value.
Lower limit = Mid-value - (Class size / 2)
Lower limit = 42 - (10 / 2)
Lower limit = 42 - 5
Lower limit = 37
Calculating the upper limit:
The upper limit is found by adding half of the class size to the mid-value.
Upper limit = Mid-value + (Class size / 2)
Upper limit = 42 + (10 / 2)
Upper limit = 42 + 5
Upper limit = 47
Thus, the upper and lower limits of the class interval are 47 and 37 respectively.
Therefore, the correct answer is option B) 47 and 37.

Upper limit = Mid-value + (Class size / 2)
Upper limit = 42 + (10 / 2)

Upper limit = 47
Thus, the upper and lower limits of the class interval are 47 and 37 respectively.
Therefore, the correct answer is option B) 47 and 37.
