Re: Normal distribution of ratio of means

Thanks for your help.

In my case, the denominator does not include zero. Moreover, the sample
size is 200 and the nature of the correlation between the two variables
can be described as follows: the denominator is the mean of cars per
household and the nominator is the mean of mercedes-cars per household.
Finally, the coefficient of variation of the mean of the denominator is
0.14211 and the coefficient of variation of the mean of the nominator
is 0.34290.

Will the ratio of these two means be approximately normally distributed
at least if the sample size was increased to 600 (so that one can
reasonably determine the 95%-confidence interval in the following way:
ratio +/- (1.96 multiplied by the standard error of the ratio))?
