Step-by-step explanation:
I'm sure that it's right
Tanya's mean score is 37.5.
Given:
Tanya's scores on 6 math tests are 33.5, 40.5, 25.5, 45.5, 48, and 32.
To Find:
Tanya's mean score.
Solution:
To solve this problem, we need to understand what mean is.
The mean of a given set of observations is simply its average.
The mean is calculated by:
Mean = (The sum of all observations)/(Total number of observations)
We need to find the mean/average of Tanya's scores on 6 math tests, all of which were out of 50. The result of the individual tests is 33.5, 40.5, 25.5, 45.5, 48, and 32.
Here the observations are the marks that Tanya scored.
Hence, the total number of observations = the total number of tests = 6.
The sum of all observations = The total sum of marks scored in each test = 33.5+40.5+25.5+45.5+48+32 = 225.
Hence, the mean score = (The sum of all observations)/(Total number of observations) = 225/6 = 37.5.
∴ Tanya's mean score is 37.5.
