Send data to calculator \begin{tabular}{|l|l|} \hline (a) What is the mean of this data set? If your answer is not an \\ integer, round your answer to one decimal place. \end{tabular}\square

Studdy Solution

STEP 1

1. The data set contains ten data points: 50,53,55,57,53,48,57,40,57,53 50, 53, 55, 57, 53, 48, 57, 40, 57, 53 .
2. The mean is calculated by summing all data points and dividing by the number of data points.

STEP 2

1. Sum all the data points.
2. Divide the sum by the number of data points to find the mean.
3. Round the mean to one decimal place if necessary.

STEP 3

List the data points:
50,53,55,57,53,48,57,40,57,53 50, 53, 55, 57, 53, 48, 57, 40, 57, 53

STEP 4

Calculate the sum of the data points:
50+53+55+57+53+48+57+40+57+53=523 50 + 53 + 55 + 57 + 53 + 48 + 57 + 40 + 57 + 53 = 523

STEP 5

Divide the sum by the number of data points (10):
52310=52.3 \frac{523}{10} = 52.3

STEP 6

The mean is already rounded to one decimal place:
52.3 \boxed{52.3}
The mean of the data set is:
52.3 \boxed{52.3}
