Answer:
P-value ≈ 0.3463
Step-by-step explanation:
Hypothesis test would be
:p=0.20
:p>0.20
We need to calculate the z-score of sample proportion and then the corresponding P-value.
z-score can be calculated as:
z=
where
- p(s) is the sample proportion of specimens yield before the theoretical point (
)
- p is the proportion assumed under null hypothesis. (0.20)
- N is the sample size (40)
Using the numbers
z=
=0.3953
and the P-value is then P(z)≈0.3463
Answer:
2
Step-by-step explanation:
7x4-3x8+2^2-6 : you have to do exponents 1st
7x4-3x8+4-6 : next you multiply 7x4 and -3×8
28-24+4-6 : you add -24+4
28-20-6 : you subtract 28-20
8-6 : you subtract 8-6
2 : thats your answer

Answer:
Yes
Step-by-step explanation:
I would say that yes, they do. The concepts are being described as normal, confident, and random. Those are describing the statistical concept the sentence is placed around.
