26/44 - 18/44 = 8/44
26 - 18 = 8
even though it is subtraction, you do not subtract the bottom numbers (denominator).
so your answer is 8/44
if you simplify it, you will get 4/22 and then 2/11
your simplified answer is 2/11 (is this on there?)
hope this helps
your question is confusing.

Answer:
98% Confidence interval: (26.939,42.461)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 34.7 bushels per acre
Sample size, n = 9
Alpha, α = 0.05
Sample standard deviation, s = 8.04 bushels per acre
Degree of freedom = n - 1 = 8
98% Confidence interval:
Putting the values, we get,
is the required confidence interval for the true mean yield.
