nts The level of nitrogen oxides (NOX) in the exhaust of a particular car model varies with mean 0.7 grams per mile and standard deviation 0.17 grams per mile. (a) What sample size is needed so that the standard deviation of the sampling distribution is 0.01 grams per mile? Hint You already have an equation that gives a relationship between the population standard deviation, the sampling distribution's standard deviation, and the sample size. Do a little algebra to solve that equation for the sample size. ANSWER: (b) If a larger sample is considered, the standard deviation for a would be (NOTE: Enter "SMALLER","LARGER" or "THE SAME without the quotes.)

Transcribed Image Text:nts The level of nitrogen oxides (NOX) in the exhaust of a particular car model varies with mean 0.7 grams per mile and standard deviation 0.17 grams per
mile.
(a) What sample size is needed so that the standard deviation of the sampling distribution is 0.01 grams per mile? Hint You already have an equation that gives a
relationship between the population standard deviation, the sampling distribution's standard deviation, and the sample size. Do a little algebra to solve that equation
for the sample size.
ANSWER:
(b) If a larger sample is considered, the standard deviation for æ would be
(NOTE: Enter "SMALLER","LARGER" or "THE SAME
without the quotes.)
