If random samples of size 525 were taken from a very large population whose population proportion is 0.3. The standard deviation

marissa [1.9K]

Answer: 0.02

Step-by-step explanation:

Given: Sample size : $n= 525$

The population proportion $P=0.3$

Then, $Q=1-P=1-0.3=0.7$

The formula to calculate the standard error is given by :-

$S.E.\sqrt{\dfrac{PQ}{n}}$

$\Rightarrow\ S.E.=\sqrt{\dfrac{0.3\times0.7}{525}}=0.02$

Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.

What is the slope and y intercept of this line? y = -4x + 7

amid [387]

Slope is -4 and y intercept is 7. Whatever the number in front of the X is, that will always be your slope. Anything added or subtracted after the x, that’s your y intercept! Hope I helped.
