Keep in mind that an inverse function is simply the reversal of the x and y coordinates of the parent function. For every (x,y) of the parent function, the inverse function has a point (y,x). With the conceptual part out of the way, finding the inverse function is relatively straight forward. If:
y=5x then the inverse function will be what you have when you solve for x and then reverse the variable labels...ie.
y=5x so
x=y/5 now reverse the variable labels...
y=x/5 this is the inverse function of y=5x or as your problem notation stated:
f^-1(x)=x/5
The confidence interval is given by

where

is the sample mean and

is the standard error of the mean. In turn, the standard error of the mean is

where

is sample size.
We have

The endpoints of the confidence interval correspond to the finite endpoints of the rejection region. That is,

for which we can solve for

. We get

which is the critical value for a confidence level of

.
The number equivalent as a mixed number would be 14/10
