Answer:
"If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?"
Step-by-step explanation:
The third option. When running the hypothesis test, you are comparing your sample size (of the campus) to the known sample size (the results given by the Pew Research Center). The results of the test give you the probability of the sample happening by random chance. We always test for equality (the sample being equal to the population), so if we reject the null, there will be evidence to suggest that the population proportion is actually more, given that the sample is an unbiased representation of the actual population
Answer:
An inverse operation is two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations.
This is a simple problem based on combinatorics which can be easily tackled by using inclusion-exclusion principle.
We are asked to find number of positive integers less than 1,000,000 that are not divisible by 6 or 4.
let n be the number of positive integers.
∴ 1≤n≤999,999
Let c₁ be the set of numbers divisible by 6 and c₂ be the set of numbers divisible by 4.
Let N(c₁) be the number of elements in set c₁ and N(c₂) be the number of elements in set c₂.
∴N(c₁) =
N(c₂) =
∴N(c₁c₂) =
∴ Number of positive integers that are not divisible by 4 or 6,
N(c₁`c₂`) = 999,999 - (166666+250000) + 41667 = 625000
Therefore, 625000 integers are not divisible by 6 or 4
