A study on students drinking habits wants to determine the true average number of alcoholic drinks all fsu undergraduate student

Sedbober [7]

Answer:

416

Step-by-step explanation:

Standard deviation is 2.6

Margin error for the problem is 0.25

Probability 95%, that means thet the siginficance level α is 1 – p

α = 1 – 0.95 = 0.05

margin of error (ME) can be defined as follows

ME = Z(α/2) * standard deviation/ √n

Where n is the sample size

Z(0.05/2) = Z(0.025)

Using a z table Z = 1.96

Now, replacing in the equation and find n

.25 = 1.96 * 2.6/ √n

0.25 = 5.096/√n

√n = 5.096 /0.25

√n = 20.38

n = 20.38^2

n = 415.5 = 416

Graph the line with slope 7 and y-intercept -7

poizon [28]

Given :-

To graph the line with slope 7 and y intercept -7.

To Find :-

The graph of the line .

Solution :-

Here since the slope of the line is 7 and y intercept is -7 , we can use the slope intercept form of the line to find the equation of the line . The slope intercept form of the line is ,

$\longrightarrow$ y = mx + c

On putting the respective values ,

$\longrightarrow$ y = 7(x) + (-7)

$\longrightarrow$ y = 7x - 7

For the graph see attachment .
