Estimated standard error for the sample mean difference= 17.93

<u>Step-by-step explanation:</u>

<u> </u>Given data,

   n=5

   variance, σ =40

Standard error = σ / sqrt (n)

                         = 40/ sqrt (5)

                         = 40/2.23

                         =17.93

Estimated standard error for the sample mean difference= 17.93

20) Which rule yields the dilation of the figure RSTU centered at the origin?
Ierofanga [76]
A) (x,y)->(4x,4y) because the x and y values are multiplied by 4 when dilated. Ex. U(-1,1) was dilated to U’(-4,4). -1 was multiplied by 4 to get -4 for the x value and 1 was multiplied by 4 to get 4 for the y value.
