Suppose at a large high school, the average AP test score for AP Statistics is 2.84 with a standard deviation of 0.45. The school decided to offer nightly study sessions and randomly chose 30 students to participate. These 30 students
averaged AP scores of 3.1.
What can be said about the effectiveness of the AP study sessions?
Roll That

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:
