The number of minutes that would make the water level be less than or equal to 64 cups is;
160 minutes.
We are given the equation;
W = -0.414t + 129.549
where;
t is the number of minutes
W is the level of water
The expression to find the amount of time it will take for the water level be less than or equal to 64 cups is;
-0.414t + 129.549 ≤ 64
Using substitution property of equality, subtract 129.549 from both sides to get;
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Using division property of equality, divide both sides by -0.414 to get;
t ≤ -65.549/-0.414
t ≥ 158.33
(sign changed to ≥ because we divided the inequality by a negative number.)
We have to approximate the inequality to get;
t = 160 minutes.

Answer:
Throw this sample out and start over again with a better sampling method
Step-by-step explanation:
Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.
Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.
Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
