Answer:
n = 3
Step-by-step explanation:
5/15 = n/9
We can solve using cross products
15 n = 5*9
15n = 45
Divide each side by 15
15n/15 = 45/15
n = 3
Answer:
-7/2 or -3.5
Step-by-step explanation:
Make the equation first
7x-1 = 5x-8
7 = -2x
-7/2 = x
Answer: 0.02
Step-by-step explanation:
Given: Sample size : ![n= 525](https://tex.z-dn.net/?f=n%3D%20525)
The population proportion ![P=0.3](https://tex.z-dn.net/?f=P%3D0.3)
Then,
The formula to calculate the standard error is given by :-
![S.E.\sqrt{\dfrac{PQ}{n}}](https://tex.z-dn.net/?f=S.E.%5Csqrt%7B%5Cdfrac%7BPQ%7D%7Bn%7D%7D)
![\Rightarrow\ S.E.=\sqrt{\dfrac{0.3\times0.7}{525}}=0.02](https://tex.z-dn.net/?f=%5CRightarrow%5C%20S.E.%3D%5Csqrt%7B%5Cdfrac%7B0.3%5Ctimes0.7%7D%7B525%7D%7D%3D0.02)
Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.
