From the information given, a right-tailed test using the z-distribution is appropriate.
At the null hypothesis, it is <u>tested if the class of statistics students is not significantly smarter than the general population</u>, that is, their mean IQ is of at most 100, hence:
At the alternative hypothesis, it is <u>tested if they are significantly smarter</u>, that is, their mean IQ is greater than 100, hence:
- We are testing if the mean is <u>greater than a value</u>, hence it is a right-tailed test.
- We have the <u>standard deviation for the population</u>, hence, the z-distribution is used.

Given:
rectangular prism = 28 cubic cm
convert to square based or cube
volume of rectangular prism = length * width * height
volume of a cube = a³
√28 = <span>3.03658897188
</span>
Amita can use 3 possible molds that are square based.
There are many examples to pick from, but one example is this:
The set of rational numbers (aka any fraction of two integers) is closed under the operation of division. Divide any two rational numbers and we get some other rational number.
However, the set of integers is not closed under division. If we divided 10 over 3, then we get 10/3 = 3.333 approximately which isn't an integer. So just because the set of integers is a subset of the rationals, it doesn't mean that the idea of closure follows suit from superset to subset.
Side note: The term "superset" is basically the reverse of a subset. If A is a subset of B, then B is a superset of A.
Division by zero is not allowed in math because a that fraction is -5 parts out of 0 total parts
if you tried to divide by zero and tried to check by multiplying it out so for example
5/10=2
5=10 times 1/2
5/0=0
5=0 times (it is imposible because anything times 0 is 0)
so the answer is C
