Question

consider the following sample data, which represent weights of sea mussels grown on the california coast, in grams: { 1.4, 1.7, 1.7, 1.8, 1.8, 1.8, 1.9, 2, 2.1, 2.2, 2.2, 2.2, 2.2, 2.2, 2.3, 2.4, 2.6, 2.9, 3 }. first, give the mean of the data set.

Explanation:

Step1: Calculate sum of data

$1.4 + 1.7+1.7+1.8+1.8+1.8+1.9+2+2.1+2.2+2.2+2.2+2.2+2.2+2.3+2.4+2.6+2.9+3=38.8$

Step2: Count number of data points

There are 19 data - points.

Step3: Calculate the mean

The mean $\bar{x}=\frac{38.8}{19}\approx2.04$

Answer:

$2.04$
