Answer:

Mid point:

= ( \frac{3 +  - 5}{2} , \:  \frac{1 + 8}{2} ) \\  = ( - 1, \: 4.5)

distance:

=  \sqrt{ {( - 5 - 3)}^{2} +  {(1 - 8)}^{2}  }  \\  =  \sqrt{64 + 49}  \\  =  \sqrt{113}  \\  = 10.6 \: units

slope:

=  \frac{1 - 8}{ - 5 - 3}  \\  =  \frac{ - 7}{ - 8}  \\  =  \frac{7}{8}

My name is Ann [436]

Answer:

(d) μ and σ²/n

Step-by-step explanation:

In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.

The standard deviation of the sampling distribution of sample means is given by

σ/√n.

The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be

(σ/√n)² = σ²/(√n)² = σ²/n
