Answer:
Mean of the data set is one of the most commonly used measures of central tendency. Basically, it means the average value of the data set. For finding it, one doesn't have to arrange the data in order. All it takes is to add them all together and divide that by the number of the data. It can be mathematically written as:
(x1 + x2 + x3 + ..... + xn) / n
This obviously means that Ashrita did the best job in calculating the mean of this data set.
Answer:
the probability is 0.4%
Step-by-step explanation:
the probability is equal to the proportion of students of X respect to the total amount of students , assuming that each student is equally likely to be chosen, thus:
Probability = number of students of X that participate / total amount of students = number of students of X / total amount of students * number of students of X that participate / number of students of X = 0.2 * 0.02 = 0.004 (0.4%)
