Finding Trimmed Mean, Probability & Statistics for Engineers & Scientist by Walpole, Solution Chap 1

Part b of question 1.1, Probability & Statistics for Engineers & Scientists by Walpole 9th edition Solution of exercise problems of Chap 1.
1.1 The following measurements were recorded for the drying time, in hours, of a certain brand of latex paint.
3.4 2.5 4.8 2.9 3.6 2.8 3.3 5.6 3.7 2.8 4.4 4.0 5.2 3.0 4.8
Assume that the measurements are a simple random sample.
(a) What is the sample size for the above sample?
(b) Calculate the sample mean for these data.
(c) Calculate the sample median.
(d) Plot the data by way of a dot plot.
(e) Compute the 20% trimmed mean for the above data set.
(f) Is the sample mean for these data more or less descriptive as a center of location than the trimmed mean?

Do we have to sort data for trimming as well?? Or we can just simply do it in the same way as written in question??
