For a sample variance of n = 36 that has a sample variance of 1,296, what is the estimated error for the sample?
lukranit [14]

Answer:

6

Step-by-step explanation:

Given :

Sample size, n = 36

Sample variance, s² = 1296

The estimated standard error can be obtained using the relation :

Standard Error, S. E = standard deviation / √n

Standard deviation, s = √1296 = 36

S.E = 36/√36

S.E = 36/6

S.E = 6

Hence, estimated standard error = 6

Graph the line with slope −2 passing through the point , 5−1.
Allisa [31]

<u>Answer:</u>

<u>y+1=-2(x-5)</u> - Point Slope Form

<u>y=-2x+9</u> - Slope Intercept Form

<u></u>

Step-by-step explanation:

We will be using point-slope formula, as attached in a picture below.

1) Plug in the slope -2 as "m" in point slope form, along with the two points, (5, -1)

<u>y+1=-2(x-5)</u>

2) Next, if you want to put the line into slope-intercept form, you will need to distribute -2 to x and -5:

y+1=-2x+10

3) Now, subtract 1 from both sides:

<u>y=-2x+9</u>
