Answer:

0.9769

Step-by-step explanation:

Given the data :

X : 7.5, 9.9, 4.8, 9, 8.1, 1.7, 3.1

Y : 35, 6, 45, 18, 20, 89, 84

The Correlation Coefficient obtained by using a graphing calculator to model the data above is : 0.9769, this means a strong positive correlation exists between the two variables.

The warranty for a particular system on a new car is 2 years. During which there is no limit to the number of warranty claims pe

const2013 [10]

Answer: by using Poisson distribution

The warranty for a particular system on a new car is 2 years

P(x=2)= 0.143

There is no limit to the number of warranty claims per car

P(X=0) = 0.449

Step-by-step explanation:

step:-1

A random variable X is said to follow a Poisson distribution if it assumes only non-negative values and its probability distribution is given by

P(X=x) = $\frac{e^{-w}w^{x} }{x!}$

here w>0 is called the parameter of the distribution

Step 2:- Given mean value of Poisson distribution = 0.8

The warranty for a particular system a new car is 2 years

P(X=x)=P(X=2)= $\frac{e^{-0.8}{0.8^{2} } }{2!}$

P(x=2)= 0.143

Step 3:-

Given mean value of Poisson distribution = 0.8

There is no limit to the number of warranty claims per car

P(X=x)=P(X=0)= $\frac{e^{-0.8}{0.8^{0} } }{0!}$

P(X=0) = 0.449

Substitute the variable and solve the problem

Answer:

don't know the answer but hope this helps

Substituting for a Variable

If you know the value that the variable is equal to, you can substitute that value in for the variable in the expression! Let's look at an example. Since we know that x=5, we can directly substitute or replace the x in the expression x+3 with a 5 to solve for y!
