Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile
kipiarov [429]

Answer: 37

Step-by-step explanation:

As per given description in the question, we have

Population standard deviation : \sigma=2.6\text{ miles per gallon}

Critical value for 98% confidence interval = z_{\alpha/2}=2.33

Margin of error : E= 1 mile per gallon

Formula we use to find the sample size :

n=(\dfrac{z_{\alpha/2}\cdot \sigma}{E})^2

i.e. n=(\dfrac{(2.33)\cdot(2.6)}{1})^2

\Rightarrow\ n=36.699364\approx37

Therefore , the number of automobiles should be used in the test =37
