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

2x + 1 = 23 what’s the answer
Arlecino [84]
Since it’s 2x+1=23 if you were to put x as 22 then add the 1 to it, it would equal 23, So the answer is 22.
