The answer to question b is 10.3923048454133
The answer is: x= 2
First apply PEMDAS
2(3x + 3)=8x+2
6x + 6 = 8x + 2
Subtract: 8x - 6x ; 6 - 2
4/2
x=2
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).
