    Having difficulty with this exercise. I need to do the following using the attached SPSS file.

    1) One Sample t-test

    - Using "Length of Stay" as the test variable, conduct a hypothesis test on whether the average length of stay is 14 days.

    - What are the steps to running this in SPSS? (I need to have the output)

    - State the hypothesis to be tested.

    - State the reject / not reject decision and conclusion.

    2) Independent Samples t-test

    - Choose any scale variable and any nominal variable with two levels from the RENAL.sav file (e.g., "Gender", "Diabetes", "Alive", "Bypass", etc.).

    - What are the steps to running this in SPSS? (I need to have the output)

    - Conduct an Independent Samples t-test on the scale variable with the nominal variable as a grouping variable.

    - State the hypothesis to be tested.

    - Test for the equality of variances (i.e. Levene's test).

    - State the reject / not reject decision and conclusion.

    3) One-Way ANOVA

    - Create a new variable AGE3 in which ages from 0-59 are recoded as 1, ages 60-69 are recoded as 2, and ages 70 and older are recoded as 3.

    - Choose any scale variable from the RENAL.sav file.

    - Conduct a One-Way ANOVA on the scale variable with AGE3 as a factor.

    - Use the Bonferroni Post Hoc test as appropriate.

    - Copy and paste the output in a Word processor in RTF format - What are the steps to running this in SPSS? (I need to have the output)

    - State the hypothesis to be tested.

    - State the reject / not reject decision and conclusion.
