There has been a trend toward less driving in the last few years, especially by young people. from 2001 to 2009 the annual vehicle miles traveled by people from 16 to 34 years of age decreased from 10,300 to 7900 miles per person (u.s. pirg and education fund website, april 6, 2012). assume the standard deviation was 2000 miles in 2009. suppose you would like to conduct a survey to develop a 95% confidence interval estimate of the annual vehicle-miles per person for people 16 to 34 years of age at the current time. a margin of error of 100 miles is desired. how large a sample should be used for the current survey?

Ответ:
1537.
Step-by-step explanation:
Formula for sample size :-
Given :![\sigma=2000](/tpl/images/0331/9143/39602.png)
Margin of error : E= 100
Critical value of 95% confidence :![z_{\alpha/2}=1.96](/tpl/images/0331/9143/6c626.png)
Now, the required sample size will be :-
Hence, the minimum sample size required = 1537.
