A 3-inch plant was crossed with a 15-inch plant, and all F₁ plants were 9 inches. The F₂ plants exhibited a 'normal distribution,' with heights of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 inches.

What ratio will constitute the 'normal distribution' in the F₂?

Hey everyone, Let's take a look at this question. Together, if we want to know the direction of the linear relationship between the body mass and density of kangaroos in Australia, which of the following statistical tests can we use? So let's recall what we know about what each of these statistical tests are used for to try to figure out which one is used when we want to find out the direction of a linear relationship between body mass and density of kangaroos. So we're trying to find a test for the direction of a linear relationship between two variables and those two variables, in this case our body mass and density of kangaroos. So when we're talking about the direction of the relationship between two variables and this relationship can either be directly or inversely proportional. We are talking about answer choice A co variance because co variance determines the direction of the relationship between two variables. And so that is the statistical test that we use, which is answer choice A co variance. The correct answer. I hope you found this video to be helpful. Thank you and goodbye.
