Since we have given that
Length of line = 100 yards
Let the x be the distance at the end of quarter nearest goal line .
According to question, He walked 41 3/ 4 yards to a yard line with the same number as the one he had just left.
So, it becomes,
Hence, the referee was 29.125 yards from the nearest goal line.

The calculations for 2, 4, 8 year can be derived as follows,
For simple interest:
S.I =
P= principle
T= Time
R= Rate
For 2 year;
S.I = = $224
Amount = $2224
For 4 year;
S.I = = $448
Amount = $2448
For 8 year;
S.I = = $896
Amount = $2896
Answer: d. 1.3333
Step-by-step explanation:
We know that the standard error of a sampling distribution is given by :-
, where = Population standard deviation.
n= Sample size.
AS per given , we have
n=81
Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-
Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.
Thus the correct answer is d. 1.3333 .
