Answer:
Option (d).
Step-by-step explanation:
Given that,
The area of a Football field is 57,600 sqft
The dimensions of Basketball court is 84ft x 50ft
We need to find what fraction of the football crowd would fit on the court. Taking ratio of the area of basket ball court to the football court as follows :
It is less than a tenth. Hence, the correct option is (d).
The probability distribution of normal distribution is given by,
f(x) =
Where a = mean = 16 and α = standard deviation = 3
In normal distribution, skewness is zero. That is, distribution is symmetric.
Therefore, mean, median and mode coincide at a point in case of normal distribution.
50th percentile is same as median or mean or mode
Therefore, 50th percentile = 16
