10. When describing the population of an organism, a group of researchers is considering three models:Model A, Model B, and Model C.a) Suppose Model A has the SSE = 44.79 and Model B has the SSE = 45.54. Which is the bettermodel based on values of the SSE? Why?Modelis the better model because the SSE is__b) Suppose Model A has R² = 0.168 and Model C has R² = 0.9555. Which is the better modelbased on the values of R² ? Why?Modelis the better model because R² is close to

2. A scientist suspects that as a person's stress level changes, so does the amount of his or her impulse buying. With N=62, r = .38. a) What are the H, and Ha for this study? b) What conclusions should he draw? c) What other calculations should be performed to describe the relationship in these data?
III. At the Olympic level of competition, even the smallest factors can make a difference between winning and losing. Previous research has found that Olympic marksmen shoot much better when they fire between heartbeats rather than during heartbeats (Pelton, 1983). The tiny vibration of a heartbeat appears to be enough to influence accuracy. A student at the University of Texas attempts to replicate the study with a group of collegiate marksmen. A group of collegiate marksmen (n = 6) fire a series of rounds while the student records heartbeats. For each shooter, a score is recorded for shots fired between and during heartbeats. Do the data support the earlier finding? Use alpha = .05.

4.) A person's muscle mass is expected to decrease with age. To explore this relationship, a researcher randomly selected 10 persons from ages 40 to 79 years old and measured their muscle mass (unit). The result is as follows: X (age) Y (muscle mass) 71 64 43 67 56 73 68 56 76 65 82 91 100 68 87 73 78 80 65 84 Based on the given data, do the following: a) Plot the scatter diagram of the given data.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
Lecture(8.8): The amount of time people engage in physical activity mat be related to health outcome. Those who report that they spend more than 15 hours are put into one while those who spend less 10 were put into another group. (Those who fall in between 10 and 15 were left out of the study); The reaearcher then ask the participants to wear a monitor for one month. The average time in minutes is recorded and shown below . Is there any evidence that on average people who watch less than 10 hours watching televsion spend more time on physical activity.?.
