Answer:
+/- 1.9983
Step-by-step explanation:
The critical values for a confidence interval for the population mean, with population standard deviation not known, are obtained from the student's t distribution.
The sample size is given as 64. The degrees of freedom will thus be;
sample size - 1 = 64 - 1 = 63
The confidence level is given as 95%. The level of significance will thus be;
100 - 95 = 5%.
The area in the right-tail will thus be 2.5%. Therefore, we looking for a t-value such that the area to its right is 2.5% and the degrees of freedom being 63. From the t-tables we have;
+/- 1.9983

Step-by-step explanation:
<u>Step 1: Define Equation</u>
8x - 3 = 2(x - 1/2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distributive 2: 8x - 3 = 2x - 1
- Subtract 2x on both sides: 6x - 3 = -1
- Add 3 to both sides: 6x = 2
- Divide 6 on both sides: x = 1/3
