Answer

Explanation:

Step1: Arrange data in ascending order

$3.25,3.25,3.66,3.83,4.44,4.52,4.57,4.69,4.74$

Step2: Calculate the median

Since there are 9 data - points (an odd number), the median is the 5th value. So, Median = $4.44$.

Step3: Calculate the sum of data

$3.25 + 3.25+3.66 + 3.83+4.44+4.52+4.57+4.69+4.74=36.95$

Step4: Calculate the mean

Mean=$\frac{36.95}{9}\approx4.11$

Answer:

Median = $4.44$ Mean = $4.11$
