Answers
1). The mean number of cars sold in a month is the same at both dealerships.
3). The total number of cars sold is the same at both dealerships.
5). The data for Admiral Autos shows greater variability.
Step-by-step explanation:
Cars Sold
Month Admiral Autos Countywide Cars
Jan 4 9
Feb 19 17
Mar 15 14
Apr 10 10
May 17 15
As per the given data, the first, third, and fifth statements are true.
To verify,
1) Let's find the mean of both the dealerships;
Admiral Autos = ∑xi/n
= (4 + 19 + 15 + 10 + 17)/5
= 13
Similarly,
Countywide Cars = ∑xi/n
= (9 + 17 + 14 + 10 + 15)/5
= 13
Thus, the mean no. of cars is same at both the leaderships.
3). Let's find the total number of cars sold is the same at both dealerships
Countywide Cars = 9 + 17 + 14 + 10 + 15
= 65
Admiral Autos = 4 + 19 + 15 + 10 + 17
= 65
Thus, the total number of cars sold is the same at both dealerships.
5). To check the variable of the data in both dealerships
Countywide Cars = Highest - Lowest
= 17 - 9
= 8
Admiral Autos = Highest - Lowest
= 19 - 4
= 15
Thus, Adimral Autos show greater variability.
