I believe it is irrational. The answer comes out to 4.942809041582063......
You can put it in a graphing calculator.

Thats it. and you just graph it

Answer:
College students' annual earnings is betweeen $2,514.33 and $3,907.67
Step-by-step explanation:
Hi, first, let´s introduce the formula that we need to use in order to find out the lower and higher limit of the interval.
Now, the only problem here is to find Z(alpha/2), so, let´s define that. Alpha is the remeining area of the normal distribution curve that is out of the limit, in other words, in this case, we need the 98% confidence interval, that means that 2% of the probs are going to be out of the range, therefore, this 2% is alpha. Since we need that the same area is removed from the left and right side of the uniform distribution curve, we need to find the value of Z in the uniform curve distribution table for 1% (that is 2%/2) and due to symmetry, we can now find the values of the interval (this means that we need the value of Z for 0.99, that is 2.33). Now, let´s find out the lower and higher limit of this interval.
So, the college students´annual earnings are between $2,514.33 and $3,907.67 with 98% of confidence.

Sorry if these are wrong! They might be flipped around... I'm not sure because I'm not very good at these
