If all possible samples of size n are drawn from an infinite population with a mean of 20 and a standard deviation of 5, then th

Ugo [173]

Answer:

25

Step-by-step explanation:

We know that the standard error of the sampling distribution of sample means is

Standard error=standard deviation/√n

√n=standard deviation/Standard error

n=(standard deviation/Standard error)²

We are given that standard deviation=5 and standard error=1. So,

n=(5/1)²

n=5²

n=25.

Thus, the required sample size is 25.

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3)

katen-ka-za [31]

Answer:

$y = \frac{2}{5}x + 3\frac{2}{5}$

Step-by-step explanation:

This line was never finished, so you finish it like this:

$\frac{5y}{5} = \frac{2x + 20}{5} → y = \frac{2}{5}x + 4$

3 = −⅖ + b

$3\frac{2}{5} = b \\ \\ y = \frac{2}{5}x + 3\frac{2}{5}$

Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅖ remains the way it is.

I am joyous to assist you anytime.
