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. part 2 of 5 next, give the median of the data set. part 3 of 5 now give the mode of the data set. if there is more than one, write them in order, separated by commas. part 4 of 5 give the midrange of the data set.

Explanation:

Step1: Find minimum and maximum values

The minimum value in the data - set $\{1.4, 1.7, 1.7, 1.8, 1.8, 1.8, 1.9, 2, 2.1, 2.2, 2.2, 2.2, 2.2, 2.2, 2.3, 2.4, 2.6, 2.9, 3\}$ is $1.4$ and the maximum value is $3$.

Step2: Calculate mid - range

The formula for mid - range is $\text{Mid - range}=\frac{\text{Minimum}+\text{Maximum}}{2}$. Substitute the values: $\frac{1.4 + 3}{2}=\frac{4.4}{2}=2.2$.

Answer:

$2.2$
