For a sample of n = 30 scores, X = 45 corresponds to z = 1.50 and X = 40 corresponds to z = +1.00. What are the values for the s
Ber [7]

Answer:

Sample mean = 30

Standard deviation = 10

Step-by-step explanation:

A system with two linear equations can be modeled with the information given in order to find the sample mean (M) and the standard deviation (s):

z=\frac{X-M}{s}\\\\1.50=\frac{45-M}{s} \\1.00=\frac{40-M}{s}

Solving the linear system:

40-M = \frac{45-M}{1.5}\\M=\frac{15}{0.5}\\M=30\\\\s=\frac{45-30}{1.5}\\s=10

The sample mean is 30 while the standard deviation is 10.

SOLVE THE SIMULATENOUS EQUATIONS Y=X-2 AND Y= 3X+5
natta225 [31]

Answer: y = x-2

y = 3x + 5

x-2 = 3x+5

x+3x = 5+2

4x = 7

x = 7/4

y = x-2

y = 7/4 - 2

y = 7-8/4

y = -1/4
