Answer: 39.308 pounds
Step-by-step explanation:
We assume that the given population is normally distributed.
Given : Significance level :
Sample size : n= 12, which is small sample (n<30), so we use t-test.
Critical value (by using the t-value table)=
Sample mean :
Standard deviation :
The lower bound of confidence interval is given by :-
i.e.
Hence, the lower bound for the 98% confidence interval for the mean yearly sugar consumption= 39.308 pounds

I AM ALSO GOING TO SHOW A SECOND WAY WITHOUT GRAPH FOR EXTRA
Given
y=6
y=3x-3
Use substitution (Substituting the value of y)
3x-3=6
Add 3 on both sides
3x-3+3=6+3
3x=9
Divide 3 on both sides
3x/3=9/3
x=3
Hope this helps!! :)
