The given in this
problem are:
99% confidence level
N = 61
Mean = 2.0 kg
Standard deviation = 4.8
Z value for a 9%
confidence interval is 2.576
Confidence Interval = mean
± Z s/ sqrt n
= 2.0 ± 2.576(4.8/sqrt 61)
=2.0 ± 2.576 (0.6145770236779006736364371988794)
= 2.0 ± 1.5832

Hey there :)

Change mixed fraction into an improper fraction


: are both even numbers, so you can further simplify by dividing by 2

To add fractions, we need same denominator to proceed. Here we have no problem since both denominators are 5


As a mixed fraction:
