One-way ANOVA is a procedure for comparing the means of several populations. It is the generalization of what procedure for comparing the means of two populations? A. pooled t-procedure OB. nonpooled t-procedure OC. paired t-test D. None of the above

Please help!!

You intend to conduct a independence for a contingency table with 6 categories in the column variable and 3 categories in the row variable. You collect data from 102 subjects. What are the degrees of freedom for the x² distribution for this test? d.f. =

When an egg is removed from the nest of a goose, the goose will roll it back into the nest with its beak. (Run a one-way ANOVA on the data. Provide a complete summary table.) Small Medium Large 10 10 15 12 14 16 11 13 17 13 14 14 15 15 17 11 16 17 12 14 14

Which statistical method can be considered as an extension of One-Way ANOVA to incorporate a "covariate"? a. two way ANOVA b. ANCOVA c. Normality Testing d. Covariance

Even if a treatment has an effect, it is still possible to obtain a sample mean after the treatment that is very similar to the original population mean. Which outcome is likely if this happens?   Group of answer choices reject H0 and make a Type I error correctly reject H0 fail to reject H0 and make a Type II error correctly fail to reject H0

You intend to conduct an ANOVA with 35 subjects, which will be divided into 3 treatment groups. (Because it will be impossible to have equal sized groups, this is referred to as an "unbalanced" single-factor ANOVA.)What are the degrees of freedom for the numerator?d.f.(treatment) = What are the degrees of freedom for the denominator?d.f.(error) =

You intend to conduct a test of independence for a con tingency table with 4 categories in the column variable and 6 categories in the row variable. You collect data from 595 subjects. What are the degrees of freedom for the x distribution for this test? d.f. =

work shown without excel would be so appreciated!

Use the data and table below to test the indicated claim about the means of two paired populations (matched pairs). Assume that the two samples are each simple random samples selected from normally distributed populations. Make sure you identify all values.     The table below shows the blood glucose of 20 students before breakfast and two hours after breakfast, using a specific insulin dosing formula to cover carbohydrates. Is there compelling statistical evidence that the specific insulin dosing formula is effective in reducing blood glucose levels? Use a significance level of 0.05. We have the differences (gain or loss), but we still need to compute the mean, standard deviation, and know the sample size for the differences (use Excel or Sheets for this computation). Once those are found, we can apply methods that are used for a 1 sample t-test.     Student Before Meal After Meal Difference 1 161 114 -47 2 196 88 -108 3 132 80 -52 4 175 96 -79 5 169 112 -57 6 138 137…
