Answer:
By given data,
Measure of central tendency is used to estimate the summary of the data set. Most commonly used measures are mean, median and mode. Where the measure of central tendency are also known as location measure.
Mean is the average of sum of all the observation divided by the total number of observations, median is the middle value that separates the ordered data into two equal halves and mode is the most repeated value
. the 1000 random variables generated by the excel.
Now Average or mean of 1000 random variables was 0.518 calculated using the excel code =AVERAGE(A1:A1000)
Since the mean value lie between the 0.4 and 0.6
Option B is correct
