Answer :
Final answer:
The best estimate for attendance A, given the provided estimates, is the weighted average of the two values which is 103.5. Option B.
Explanation:
The question seems to be a bit confusing due to the typos and irrelevant parts, but if we focus on the provided additional information about attendance A,
we can infer that the best estimate for attendance A seems to be the weighted average of the two given estimates, taking into account their respective uncertainties:
A = {1 x 105 + 1 x 102}{1 + 1} )
To calculate this, we add the values of 105 and 102 and then divide by 2 since there is an equal weight (1) given to both estimates.
The calculation yields:
A = (105 + 102) / 2 = 207 / 2 = 103.5
Therefore, the best estimate for the attendance A is 103.5.
This seems to indicate that we are looking at a statistics problem that involves calculating the mean or average of a set of data.
Hence, the correct answer is: Option B.
The complete question is:
There are 40 students in section A of class 10th and 54 in section B of class 10th. What is the best estimate for attendance A?
a) 94
b) 103.5
c) 125
