Question

Samples of DNA are collected, and the four DNA bases of A, G, C, and T are coded as $1,2,3$, and 4, respectively. The results are listed below. Construct a $95 \%$ confidence interval estimate of the mean. What is the practical use of the confidence interval? $$ \begin{array}{llllllllll} 2 & 2 & 1 & 4 & 3 & 3 & 3 & 3 & 4 & 1 \end{array} $$

Step 1

The mean (average) is calculated by adding up all the numbers and then dividing by the number of numbers. In this case, the mean is $(2+2+1+4+3+3+3+3+4+1)/10 = 2.6$. The standard deviation is a measure of how spread out the numbers are. It's calculated by Show more…
