Answer:
p= 0.9995 and we can conclude that students receiving aid is more than 50% according to the sample results in 2% significance level.
Step-by-step explanation:
: less than or equal 50% of students at his college receive financial aid
: more than 50% of students receive financial aid.
According to the nul hypothesis we assume a normal distribution with proportion 50%.
z-score of sample proportion can be calculated using the formula:
z=
where
- X is the sample proportion (0.65)
- M is the null hypothesis proportion (0.5)
- s is the standard deviation of the sample (
) - N is the sample size (120)
then z=
≈ 3,29
thus p= 0.9995 and since p<0.02 (2%), we reject the null hypothesis.
Answer: B. There are no integers that are whole numbers.
<u>Step-by-step explanation:</u>
A. Whole numbers are never irrational. TRUE
B. There are no integers that are whole numbers. FALSE!
There ARE integers that are whole numbers because Integers are positive and negative whole numbers.
C. There is only one whole number that is not a natural number. TRUE
Whole Numbers: 0, 1, 2, 3, ...
Natural Numbers: 1, 2, 3, ...
D. Natural numbers cannot be negative. TRUE
I’m confused? What do u mean?
Answer:
Step-by-step explanation:
y = a * x(x - 3)(x + 1)^2
2,12 is used to find the value of a
y = a (2)(2 - 3)(2 + 1)^2
12 = a (2)(-1)(3)^2
12 = a (2) (-1) (9)
12 = - 18*a
12/-18 = a
a = - 2/3
y = (-2/3)*x*(x - 3)(x + 1)^2
THATS A LOT
