Answer: The options are given below:
A. Half of his classmates spend exactly $38 per month buying snacks.
B. If the amount spent on snacks per month by all his classmates is leveled, that amount would be $38.
C. The majority of his classmates spend $38 per month buying snacks.
D. Half of his classmates spend more than $38 per month buying snacks
The correct option is B.
Explanation: Mean can be defined as the sum of all the observations in a sample, divided by the total number of observations. Mathematically, it is expressed as:
Mean = sum of observations / total number of observations
From the question above, we have:
Amount of money everyone spends buying snacks each month is equal to a mean of $38.
What this means is that the average amount of money spent by everyone is equal to $38.
Therefore, If the amount spent on snacks per month by all his classmates is leveled, that amount would be $38.
So, we can conclude by saying, if one classmate paid above $38, and another paid below $38, it will be nullified by leveling the amount paid by all the classmates while calculating the mean.
Answer:
If the amount spent on snacks per month by all his classmates is leveled, that amount would be $38.
Explanation:
Mean is a measure of central tendency, that is it is used to measure how a range of values are centrally related.
The mean is calculated by taking the average of a range of values. The mean expresses a characteristic that is shared by a particular population.
Mean is represented mathematically as
Mean= Sum of items ÷ number of items
So the mean amount spent on snacks is a levelled value of what Luke's classmates spend.
