    Problem #1

    T-tests compare two groups. For each question, please divide your independent variable into two groups. I expect a statement regarding which variables you used to as the dependent and independent variables to answer the question, a description of how you divided your groups, the means of the groups, the t-value, and the significance. You also need to interpret these results.

    Remember: Use the correct values (can equal variances be assumed?)
    The significance is given as a two-tailed result. Is this the result you should report?

    1. Do people who read ingredients on food labels choose healthier items when eating at home?

    HC3- I usually read ingredients on food labels (Independent variable)
    HOH- When I eat at home, I eat healthy (Dependent variable)

    Steps:
    1. Write the null (Ho) and alternative H1) hypotheses:
    H0: HC3 = HOH
    There is no significant difference in the responses between people who read ingredients on food labels and their choice of healthier items when eating at home.
    H1: HC3 ? HOH
    There is a significant difference in the responses between people who read ingredients on food labels and their choice of healthier items when eating at home.

    2. Determine if this is a one-tailed or a two-tailed test. Because the hypothesis involves the phrase "different" and no ordering of the means is specified, this must be a two tailed test. (For more information, access this link at the University of Dayton, http://academic.udayton.edu/gregelvers/psy216/spss/ttests.htm).

    3. Since the study is based on perception of the respondents, you can use ? = .05. This means that you are 95% accurate in your analysis.

    4. The paired samples t-test can be used to determine if two means are different from each ...
