Hello! And thank you for this question!
For this equation all you will do is use the distribution property.
6*y + 6 * 8
6y + 48
Final Answer:
6y + 48
The Z-value for a 90 percent confidence is 1.645
To find the sample size use the formula:
Sample size = Z-value x SD / error)^2
Using the provided information:
SD = 4,000 miles
Error = 500 miles
Sample size = ((1.645) (4000)/ 500)^2 = 173.18 = 174
