Answer:
The 95% confidence interval for population mean is (18.19, 23.81).
Step-by-step explanation:
The confidence interval for population mean using the Student's <em>t</em>-distribution is:
Given:
The critical value of <em>t</em> for <em>α </em>= 0.05 and degrees of freedom, (<em>n</em> - 1) = 19 is:
Compute the 95% confidence interval for population mean as follows:
Thus, the 95% confidence interval for population mean is (18.19, 23.81).
Prime factorization can be obtained by the factor tree
72=2*36=2*(2*18)=2*(2*(2*9))=2*2*2*3*3=2^3*3^2
