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:

127 137

If you divide the foam into 2 rectangular prisms, you will get a rectangular prism with dimensions of 1 * 2 * 7, and another prism with dimensions of 1 * 3 * 7. You find the separate volumes of each, and get 14 ft^3, and 21 ft^3. You add these together to get 35 ft^3
