    told that the task is easy. What test should be used to see if there are differences between the two groups with regards to the time it takes to solve

    the puzzle?

    Z-Test

    T-Test for One Sample

    T-Test for Independent Samples

    One Variable Chi Square

    One-Way ANOVA

QUESTION 6

  1. A researcher wants to test whether there is a relationship between hair color (brown, blonde, black) and susceptibility to a skin rash (gets

    rashes/doesn’t get rashes). Three hundred subjects are used for this investigation. Which statistical test should be used to determine whether there

    is a relationship between the two variables?

    T Test for Independent Samples

    Factorial ANOVA

    T-Test for Related Samples

    One-Way ANOVA

    Two-Variable Chi-Square Test

    For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...
