Three different exercise regimens are being evaluated. Your fitness center enrolls 60 participants and measures weight loss at the end of a 10 week period. Weight loss is defined as: 1-lost weight; 0-did not lose weight. What is the most appropriate test?
A. Independent samples t-test
B. Paired t-test
C. One way ANOVa
D. Regression Analysis
E. Chi-square Test of Independence

A researcher created three groups based on participants BMI: normal weight, overweight and obese. The hypothesis being tested is that the three groups differ in the mean number of artificially sweetened drinks consumed weekly. Which statistical test might the researcher use, assuming a reasonable normal distribution of values? Group of answer choices One way ANOVA A chi-squared test An independent group t test A repeated measures ANOVA
For the following questions, identify the type of test that should be used. Simply use the corresponding letter: A) One-sample z test (for a mean); B) One-sample t-test; C) One-sample z-test for a proportion (or a chi-squared goodness-of-fit); D) Chi-square goodness of fit (and a z-test is not appropriate); E) Two-sample z-test for a difference between proportions (or a chi-squared test for independence); F) Chi-square test for independence (and a z-test is not appropriate); G) Simple regression; H) Multiple regression;...

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...
Problem 3 Weight reduction is an important goal for the management of type 2 diabetes (T2D) among overweight patients. A 2016 study evaluated the effect of oat intake (a cereal grain) for overweight T2D patients. A total of 298 overweight T2D subjects (BMI of at least 24 kg/m2) were randomly assigned to follow one of 4 dietary guidelines for 30 days, as shown in the diagram below. The two “oats” groups ate the same healthy diet as the “diet" group,...
Which Test those cases should use? A: one sample z-test B: one-sample t-test C: t-test for the difference between means for two related samples D: t-test for the difference between means for two independent samples with homogeneity of variance E: t-test for the difference between means for two independent samples with heterogeneity of variance F: a one sample z-test for proportions (or a chi-square goodness of fit) G: chi-square goodness of fit only (where a one sample z-test of proportions isn’t appropriate) H: a two-sample z-test...

A diet center claims that it has the most effective weight loss program in the region. Its advertisements say, “Participants in our program lose more than 5 pounds within a month.” Six clients of this program are weighed on the first day of the diet and then one month later. Let the difference be defined as Weight on First Day of Diet minus Weight One Month Later. (You may find it useful to reference the appropriate table: z table or t table) ClientWeight on First...
