Number of rafts needed</h3>
Using this formula
There are 136 people waiting for a river raft ride each raft holds 8 people.
Number of rafts needed=Number of people/Capacity of raft
Where:
Number of people = 60
Capacity of raft = 15 people
Let plug in the formula
Number of rafts needed=60/15
Number of rafts needed=4 rafts needed
Therefore if raft holds 15 people. how Silvia's work can be used to find the number of rafts needed is: total number of people/<em>Number </em>of people holded by each raft.

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.
