First, change the decimal to a fraction by putting it over 1000:
Now find a common denominator of 625 and 1000. The simplest to find and divide by is 5. So begin by dividing them each by five until you have a completely simplified fraction:
The answer is

Answer:
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The upper end of the interval is the sample mean added to M. So it is 2.89 + 0.04 = 2.93.
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
