There are 7 variables listed: Choose TWO variables that you feel are correlated and explain why you feel that they are correlate

d. Do you suspect the relation is positive or negative. Why? Which would be considered the independent variable, which the dependent variable? Why?
Run a regression analysis in Excel and provide the results in your response. Looking at the r squared value, explain what this indicates about the strength of the relation.

In Illinois, 9% of all drivers arrested for DUI (Driving Under the Influence) are repeat offenders; that is, they have been arre
Veseljchak [2.6K]

Answer:

a) 21.58% probability that exactly 3 people are repeat offenders

b) 97.91% probability that at least one person is a repeat offender

c) 3.69

d) 1.83

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

9% of all drivers arrested for DUI (Driving Under the Influence) are repeat offenders

This means that p = 0.09

41 people arrested for DUI in Illinois are selected at random.

This means that n = 41

a. What is the probability that exactly 3 people are repeat offenders?

This is P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{41,3}.(0.09)^{3}.(0.91)^{38} = 0.2158

21.58% probability that exactly 3 people are repeat offenders

b. What is the probability that at least one person is a repeat offender?

Either none are repeat offenders, or at least one is. The sum of the probabilities of these outcomes is 1. So

P(X = 0) + P(X \geq 1) = 1

We want P(X \geq 1).

Then

P(X \geq 1) = 1 - P(X = 0)

In which

P(X = 0) = C_{41,0}.(0.09)^{0}.(0.91)^{41} = 0.0209

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0209 = 0.9791

97.91% probability that at least one person is a repeat offender

c. What is the mean number of repeat offenders?

E(X) = np = 41*0.09 = 3.69

d. What is the standard deviation of the number of repeat offenders?

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{41*0.09*0.91} = 1.83

Can anyone help? Will give Brainly and 45 pts &lt;3

Solving this involves substitution of values into the given formula and applying basic arithmetic.

<u>Weight of Car is 2.1 tons</u>

We are told that the dimensions of the rectangle are 7in and 5in.

Formula for area of a rectangle is;

A = Length x breadth

Thus;

A = 7 × 5

A = 35 in²

We are also given;

Air pressure; P = 30 psi

A car has 4 tires and so;

Number of tire; N = 4

We are told that formula for weight of the car in ton is;

W = APN/2000

Plugging in the relevant values;

W = (35 × 30 × 4)/2000

W = 2.1 tons
