Understanding Two Terms: At Least vs. No More Than
Students often mix up these terms when answering probability questions! Here are two nonthreatening
English examples. Just use the same interpretation when working with numbers in a statistics class.
At Least
A student says: This chapter is very difficult. I think I need
“at least”
7 hours of study time before I fully
understand it.
Analysis: At least 7 hours implies that anything equal to or greater than 7 hours will be sufficient. On the
other hand if he spends less than 7 hours, he will not be successful.
Hours ≥ 7 will lead to success.
hours < 7 will not lead to success.
No More Than
I am at a store with my daughter who is now on an allowance and can’t use my hardearned dollars very
freely when she is shopping. She picks up a skirt and it does not have a tag, so she must look for a
manager to ask the price. She tells me that she really likes it, but she would pay “
no more than”
$10 for
it.
This is the end of the preview.
