Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as

Answer:
The answer is B) because 10 and 12 ounces of yogurt equals to 5 free rewards that they are both the same.
We have to determine the value of
= (5(9)+6) + (5(10)+6) +(5(11)+6) + .......... + (5(21)+6)
= 51+56+61+66+ ........ + 111
Since, the common difference is 5, hence this series is in arithmetic progression.
Sum of AP is given by the formula:
Since, there are 13 terms.
=
=
=
=
= 1053
Therefore, the sum of the series is 1053.
So, Option G is the correct answer.
