Briefly discuss how to determine the relationship between two nominal variables, and how to determine the relationship between two numerical variables. (Hint: Talk about the methods in general. No additional calculation is required.)

I attached a picture of the question; I have most of it but I want to double check

During one month, the rate for renting a particular car model was $65.94 per day plus 20¢ per mile. For a 1-day rental, let x denote the number of miles driven and let y denote the total cost, in dollars. Complete parts (a) through (e) below. a. Find the equation that expresses y in terms of x. y= (Type integers or decimals for any values in the expression. Do not include the $ symbol in your answer. Do not round.) b. Determine bo and b₁. The value of bo is (Type an integer or a decimal. Do not include the $ symbol in your answer. Do not round.) The value of b, is (Type an integer or a decimal. Do not include the $ symbol in your answer. Do not round.) c. Construct a table for the x-values 50, 100, and 250. Cost ($) y Miles X 50 100 250 (Simplify your answers. Type integers or decimals. Do not round.) d. Draw the graph of the equation in part (a) by plotting the points from part (c) and connecting them with a line. Choose the correct graph below.

Which of the following choices most correctly pairs precision and accuracy with the statistical calculation performed to measure it?       Precision and accuracy are both measured with percent error.     Precision and accuracy can only be found by graphing the data and finding R2.     Precision is measured with percent error. Accuracy is measured with RSD.     Precision and accuracy are both measured with RSD.     Precision is measured with RSD. Accuracy is measured with percent error .

Imagine you score a x=54 on an exam. What set of parameters would give you the highest grade?   A: ?= 52 and ?=2  B: ?= 50 and ?=8 C:  ?= 50 ?=2  D: ?=52 and ?=8

Suppose you wanted to know if there was a relationship between time spent on the internet and IQ. Which model would make the most sense and what would it look like? A Internet predicting IQ, with internet on the left-handed side of the equation and IQ on the right. B IQ predicting internet, with IQ on the left-handed side of the equation and internet on the right. C IQ predicting internet, with internet on the left-handed side of the equation and IQ on the right. D Internet predicting IQ, with IQ on the left-handed side of the equation and internet on the right.

If P(E) = 0.45, P(E or F) = 0.70, and P(E and F) = 0.05, find P(F). P(F) = (Simplify your answer.)

In regression analysis, the independent variable is   a. used to predict other independent variables   b. used to predict the dependent variable   c. called the intervening variable   d. None of these answers is correct.
