    1. For the following data on 10 persons, construct a scatterplot showing the relationship between age and number of children, and describe the relationship in verbal terms.

    Person (i) Age
    (X1) Number of
    Children (Yi)
    1 42 5
    2 26 2
    3 38 2
    4 23 1
    5 21 0
    6 19 0
    7 79 6
    8 25 2
    9 75 4
    10 67 3

    2. Suppose social psychologist collects the following data from five subjects: their scores on a test measuring the extent to which they trust other people and the number of altruistic acts they performed in the last month. Create a bivariate regression equation for these variables, treating altruistic acts as the dependent variable.

    Subject Trust Altruistic acts
    1 70 5
    2 85 8
    3 92 12
    4 64 3
    5 79 7

    3. For the data in question 1, calculate the correlation coefficient, the coefficient of determination, and the coefficient of non determination. What can you conclude?

    Solution:

    Scatter plot of Age and number of child data does indicates any pattern in the data so the distribution of the data points indicates a positive linear relationship between the two variables.

    2. Suppose social psychologist ...
