17. The Wechsler Adult Intelligence Scale (WAIS) is common "1Q test" for adults. The distribution of WAIS scores for persons over 16 years of age is approximately normal with mean of 100 and standard deviation 1.5. Let 8=the mean of WAIS score in a random sample of 10 people over 16 years of age. a. Calculate the mean and standard deviation of the sampling distribution of R.

b. Interpret the standard deviation from part (a)

C. What is the probability that the average WAIS score is 105 or greater for a random sample of 10 people over 16 years of age? Show your work.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

i think the amount would be $140.62

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
