r = -.23 between the number of interfering mothers-in-law and the number of happy marriages.
How do I interpret the way the variables "go together?"
The coefficient of correlation is denoted by the term 'r' here. It can range from -1 to +1. As the value gets closer to zero, the less is the relationship between variables. When r is positive, it means that the variables have a positive relationship (as one increases, the other one also increases) and when r is negative, it means that they have an inverse relationship (as one increases, the other one decreases). Here, the value is negative. That is, as the number of interfering mother in laws increases, the number of happy marriages decreases. But this relationship is not strong since the value is only -.23, which is near to zero.

Question 3 A researcher is interested in the relationship between the birth weights of infants and mothers' smoking habits. He uses the birth weight of an infant (ounces) and the average number of cigarettes the mother smokes per day during the pregnancy as the dependent and independent variables, y and x, respectively. Using a sample of size (1388 the following model is obtained by the method of least squares: y-119.770.514.x (3.15) (0.13) SE e the figures in brackets are the...
How do laws originate? Explain the differences between various sources of law and describe the branches of government and their roles in creating, administering, and enforcing law. In addition, what are the differences between contract law and tor law? What about public law versus private law? Please write clearly and I need source too. Thank you so much (Subject is Med Law and Ethic)
In mathematical language, Newton's Law of Gravity expresses the force of gravity, F, between two objects in the following way: F= (GMm)/r^2where M is the mass of one object, m is the mass of the other object, r is the distance between the two objects, and G is the gravitational constant. Which of the following statements best describes what this formula says?a)The force of gravity between two objects depends on the product of their masses and the distance between them.b)The...

1. How many different ways can you have r numbers 1 sum up to a number n? These are called compositions of a number n and it is easy to calculate from our understanding of binomial coefficients. So the number of compositions of 4 into 3 parts will be 1+1+2, 1+2+1, and 2+1+1. Note how we think of 1+1+2 and 1+2+1 as different-because in the first case, the first number is 1, second is 1 and third is 2, while...
I NEED HELP~ ACTIVITY 4 Activity 4: Newton's Law of Gravity: The force of gravity between any two objects of masses mi and m2, separated by a distance of r is given by Gmm 1. Calculate the average gravitational pull on Pluto (use r - semi-major axis). 2. Approximate Pluto's orbit to a circle (with radius semi-major axis) and determine Pluto's tangential speed using what you know about rotational motion. How does this value compare with the values you found...
IMPORTANT STEP: For each experiment, Fixed Phen and Fixed Fe, write the Beers Law equation for each sloped series trend line. Do not use the y-intercept term, and do not use y or x as the variables. Use the chemical variables A for absorbance and the reactant concentration symbolism, []. For example, if the trendline equation for the varying mmoles of iron (II) sulfate is y-1070x, then the equation you would use is: A-1070 [Fe] A 1062 el If the...
Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...
