Answer:
96 full miles.
Explanation:
[tex]33=17.50+0.16m\\0.16m=15.5\\m=\frac{15.5}{0.16}\\m=96.875[/tex]
We intend to estimate the average driving time of a group of commuters. From a previous study, we believe that the average time is 68 minutes with a standard deviation of 12 minutes. We want our 90 percent confidence interval to have a margin of error of no more than plus or minus 1 minutes. What is the smallest sample size that we should consider
Answer: The smallest sample size would be 392.
Explanation:
Since we have given that
Standard deviation = 12 minutes
Mean = 68 minutes
Margin of error = [tex]\pm 1[/tex]
At 90% confidence interval, z = 1.65
So, the smallest sample size that we should consider would be
[tex]n=(\dfrac{z\times \sigma}{ME})^2\\\\n=(\dfrac{1.65\times 12}{1})^2\\\\n=(19.8)^2\\\\n=392.04\\\\n=392[/tex]
Hence, the smallest sample size would be 392.
