Determine if the following statements are true/false
If the statement is false, either correct it or briefly explain why it is false.

________ The correlation coefficient indicates the change in y associated
with a unit change in x.

________To conduct a valid regression analysis, both x and y must be
approximately normally distributed.

________ All data points will fit the regression line exactly if the sample
correlation is either +1 or −1.

_________ If r > 0, then as x increases, y tends to increase.

_________ The correlation coefficient can be used to detect any relationship
between two variables.

_________ If r is very close to either +1 or −1, then there is a cause and
effect relationship between x and y.

Determine whether each of the following statements is true or false. If the statement is false,...

Determine whether each of the following statements is true or false. If the statement is false, modify and rewrite it so that it is a true statement. a. When a molecule has two, degenerate, “infrared active”, vibrational modes, the two vibrational modes will show absorptions at different frequencies in the infrared spectrum. b. For a given substance, strong intermolecular forces between molecules of the substance can cause peak broadening of some of the absorptions in the infrared spectrum of the...

1. Determine if the following statements are true or false. If a statement is true, prove it in general, If a statement is false, provide a specific counterexample. Let V and W be finite-dimensional vector spaces over field F, and let φ: V → W be a linear transformation. A) If φ is injective, then dim(V) ≤ dim(W). B) If dim(V) ≤ dim(W), then φ is injective. C) If φ is surjective, then dim(V) ≥ dim(W). D) If dim(V) ≥...

Answer the given statements as True or False. If the statement is false, correct it so it becomes a true statement. 1. The neutral axis can be found at a distance ‘y’ (where y>0) from the centroidal axis of a member. 2. The centre of curvature can be found at a radial distance (rho) from the neutral axis of a member in pure bending. 3. When developing generalized equations for stress transformations, we must consider stresses on only the horizontal...

Determine if the following statements are true or false. In either case, provide a formal proof...

Determine if the following statements are true or false. In either case, provide a formal proof using the definitions of the big-O, big-Omega, and big-Theta notations. For instance, to formally prove that f (n) ∈ O(g(n)) or f (n) ∉ O(g(n)), we need to demonstrate the existence of a constant c and a sufficient large n0 such that f (n) ≤ c g(n) for all n ≥ n0, or showing that there are no such values. a) 10000n2 ∈ O(n4)....

For each of the following statements, determine whether the statement is true or false. If you say the statement is true, explain why and if you say it is false, give an example to illustrate. (a) If {u, v} is a linearly independent set in a vector space V, then the set {2u + 3v, u + v} is also a linear set independent of V. (b) Let A and B be two square matrices of the same format. Then...

2) True or False (If statement is false, correct it so that it is true) a) Polymers make up an exciting class of biomaterials. Polyethylene is a wonderful example of a simple ceramic that can be used in multiple applications by modifying its chemical structure. It tends to be bioactive when used by itself as an implant, but it becomes even more bioactive when 10 vol% Calcium Carbonate is added to it. Teflon can be used as a vascular graft...
