The equation of the line is y=2x-3.

It is required to find the equation of the line.

<h3>What is straight line?</h3>

A straight line is just a line with no curves .The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

Given:

The slope-intercept form of a line is

y = mx +c

where c is the intercept and m is the slope.

According to given question we have,

slope =2

y - intercept=-3

The equation of the line

y=2x-3

Therefore, the equation of the line is y=2x-3.

The mean income per person in the United States is $50,000, and the distribution of incomes follows a normal distribution. A ran

sergij07 [2.7K]

Answer:

Yes. There is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average

Step-by-step explanation:

Given the following;

$\alpha=Significance \ Level=0.05\\n=10\\\bar X=60000\\\ s=sample\ \sigma=10000$

#We set our hypothesis as:

$H_o:\mu\leq 50000\\H_a:\mu>50000$

The rejection region of either hypothesis:

$P(t>t_o)=0.05$ , we determine the critical values for this probability in the T distribution table;

$t=1.833$

=>We reject for all values greater than 1.833, t>1.833.

#We now determine the value of the test statistic as:

$t=\frac{\bar X-\mu_o}{s/\sqrt{n}}\\\\=\frac{60000-50000}{10000/\sqrt{10}}\\\\=3.1623$

We find that:

$t=3.1623>1.833,\ \ \ Reject \ H_o$

Hence, there is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average.
