There is no question that both nature (genetics) and nurture (environment) play a role in human characteristics and behavior. One way to tease apart the effect of nature and the effect of nurture is to study children who have been adopted at birth. These children are unique in that they received the genetic influence from their birth parents and the environmental influence from their adoptive parents. For example, a research study can be conducted to see if the amount of time a child spends watching TV is more correlated with the TV-watching time of his/her birth parent or adoptive parent. If the TV-watching time of the child is more correlated with the birth parent’s TV-watching time, it means that the propensity to watch TV might be genetically determined to a larger extent compared to environmental influence. If it’s more correlated with the adoptive parent’s TV-watching time, then it means that the propensity to watch TV might be influenced by the behavior of the adoptive parent to a larger extent.

Use the following dataset to answer the questions below:

Calculate the Z scores for all the data points for the children and their birth parents. (please show work for at least a few so I can understand how to do them)

Explain the direction and strength of the relationship based on the r.

Calculate the Z scores for all the data points for the adoptive parents. (please show work for at least a few so I can understand how to do them)

Explain the direction and strength of the relationship based on the r.

Graph the following linear inequalities on the digital graph paper worksheet Problem 10.

Show ALL your algebra steps that are required to determine the X and Y intercepts for both equations in the text box. From the MS Excel ribbon > Insert > Shapes > Lines.

Line # X coefficient Y coefficient “RHS”

1 3 4 ≤ 36

2 6 3 ≤ 48

3 1 0 ≤ 7

Use the text box for you answer. Solve algebraically, showing ALL steps, for the solution, or “intersection” of:

1. Equation 1 and equation 2.

2. Equation 1 and equation 3

3. Equation 2 and equation 3

4. What extreme points bound the feasible region? List the coordinates

If needed, show solutions in decimals, not fractions. Show the final X and Y values in BOLD.

A special deck of 24 cards consists of 4 eights, 4 nines, 4 tens, 4 aces, 4 queens and 4 kings. A game consists of dealing a card from the 20 and winning or losing the money as in the following image. a) Determine the probabilities of all possible outcomes on the amount of money you could earn or lose. (As in the probability distribution – no graph necessary)

- if the card is 8,9, or 10 you lose the dollar equivalent to the face value of the card

- if the card is a face card you win $10

- if the card is an ace you lose $20

b) What’s the expected amount of money won or lost for this game?

c) Is this game considered a fair game? Justify your answer.

Some species of rodents live on average 6 years. In the first two years of life they do not reproduce and only 20% of the females born alive reach 2 years of age. Between the third and fourth year females have 1 daughter on average and their survival is 50%, while in the las two years they have 2 daughters on average. If in an ecosystem there is initially a population of 10 females between 0 and 2 years old, 4 between 3 and 4 years and 3 with more than 4 years. After 3 years the estimated population of females will be:

Write a program in C that does the following:

1. Declares an array called numbers_ary of 6 integer numbers.

2. Declares an array called numbers_ary_sq of 6 integer numbers.

3. Reads and sets the values of numbers_ary from the keyboard using a loop.

4. Sets the values of numbers_ary_sq to the square of the values in numbers_ary using a loop.

5. Displays the values of numbers_ary and the values of numbers_ary_sq beside each other using a loop.
