On a statistics examination the mean was 78 and the standard deviation was 10. (a) Determine the standard scores of two students

Ludmilka [50]

Answer:

a) Grade = 93, Standard score = 1.5

Grade = 62, Standard score = -1.6

b) Standard scores = 0.6, Grade = 84

Standard scores = 1.2, Grade = 90

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 78

Standard Deviation, σ = 10

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) Grade = 93

$\text{Standard score } = \displaystyle\frac{93-78}{10} = 1.5$

Grade = 62

$\text{Standard score } = \displaystyle\frac{62-78}{10} = -1.6$

b) We have to find grades of student

Standard scores = 0.6

$\displaystyle\frac{x-78}{10} = 0.6\\\\x = (0.6)(10)+78 \\x = 84$

Grade = 84

Standard scores = 1.2

$\displaystyle\frac{x-78}{10} = 1.2\\\\x = (1.2)(10)+78 \\x = 90$

Grade = 90

Step-by-step explanation:

The first expression is not true as the side labelled m in figure I corresponds to the side labelled 1.05 in figure II the side labelled but as for the the other set in the comparison i.e 0.7/1.4 it should start with the side that from figure I in the order in which they appear in the first ratio. The sides in the other ratios in the options correspond to each other and appear int the order in which the first ratio in each set appears
