A psychologist is investigating the relationship of ambient temperature and water consumption. She chooses 20 participants and measures how much water they consumed throughout the course of a day and what the high temperature was for that day. The data is presented below Temperature Water consumption (oz) 75 83 85 85 92 97 16 20 25 27 32 48 34 35 87 78 41 45 19 41 38 23 89 98 78 84 71 For this data you will:
Use the SPSS program to calculate the correlation and create a scatterplot
How would you describe this relationship? (both strength and direction, in your own Provide the appropriate output box . simple words)
Are these variables truly related or could there be a third variable at play?
Mediating or confounding variables Calculate the regression equation fshow your work) .
How much water should someone drink if the high temperature for that day was 70o degrees?
Calculate the proportionate reduction in error

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
