Please help me answer each blank questions with provided answer choices. thank you :)

1. Hypotheses for ANOVA

In a hypothesis test for ANOVA, you are interested in the significance of the difference between _______ CHOICES ARE: SAMPLE VARIANCES, SAMPLES, POPULATION MEANS, POPULATION VARIANCES. You assume that you have ____ CHOICES ARE: ISOLATEDINDEPENDENT, DEPENDENT, UNBIASED ______ CHOICES ARE: STRATIFIED, MINIMAL, RANDOM, UNEQUALsamples from populations that are____ CHOICES ARE: EXPONENTIALLY, EQUALLY, NORMALLY, UNEQUALLY, distributed with ___ CHOICES ARE: INDEPENDENT, EQUAL, RANDOM, UNEQUAL, variances. The test is designed to be used with____ CHOICES ARE: INTERVAL-RATIO, NUMERICAL, ORDINAL, NOMINAL -level dependent variables.

What is the null hypothesis in an ANOVA? CHOOSE ONE:

H0: Not all population means are equal.

H0: Some of the population means are equal.

H0: All population means are equal.

H0: All population means are different.

What is the alternative hypothesis in an ANOVA?

H1: All population means are equal.

H1: At least one of the population means is different.

H1: Some of the population means are equal.

H1: All population means are different.

The F-test statistic is formed by taking the____ CHOICES ARE: PRODUCT, RATIO, SUM, of two separate estimates of ___ CHOICES ARE VARIANCE, STANDARD DEVIATION, MEAN, CORRELATION, where the estimate in the numerator is derived from the____ CHOICES ARE VARIATION WITHIN CATEGORIES, SUM OF VARIABLES, OVERALL AVERAGE, VARIATION BETWEEN CATEGORIES and the estimate in the denominator is derived from the_____ VARIATION WITHIN CATEGORIES, OVERALL AVERAGE, SUM OF VARIABLES, VARIATION BETWEEN CATEGORIES. The sampling distribution is the___ CHOICES ARE F, P, T, Z distribution with ____ N-1, N-k, N, k-1 degrees of freedom within categories and _______ N-1, N-k, N, k-1 degrees of freedom between categories.

Once you compute the F(obtained) statistic for your data, you compare its value with F(_____ choices are: critical, dependent, obtained, alternative) determined by the given alpha level and the degrees of freedom. If the test statistic is in the critical region, you___ choices are: support, reject, reevalutate, confirm the null hypothesis and conclude that there___ choices are: is not OR isa significant difference between the means.
