Students applying to law school must take the LSAT exam. Since competition for acceptance is stiff, many students take a course

Anestetic [448]

Answer:

a) Dependent

b) H0: µd = 0

Ha: µd > 0

c) Stat --> Basic Statistics ----> Paired t. then select samples 1 , 2 to get the required output

d) Not enough data

Step-by-step explanation:

Using values found in MINITAB 19

a) The samples are dependent and this is because the title of the test is the same ( i.e. A group of students given the LSAT )

b) Appropriate hypothesis

H0: µd = 0

Ha: µd > 0

c) The Minitab procedure to be used to test the hypothesis is

click on Stat --> Basic Statistics ----> Paired t. then select samples 1 , 2 to get the required output

d) Not enough data to create a probability plot

Jeffrey calculated the slope between two pairs of points. He found that the slope between -5, 6 and -3, 2 is -2. He also found t

Cerrena [4.2K]

Answer:

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between -5, 6 and -3, 2

substitute the values in the formula

$m=\frac{2-6}{-3+5}$

$m=\frac{-4}{2}=-2$

step 2

Find the slope between (-1, -2) and (0, -4)

substitute the values in the formula

$m=\frac{-4+2}{0+1}$

$m=\frac{-2}{1}=-2$

step 3

Find the slope between (-3, 2) and (0, -4)

substitute the values in the formula

$m=\frac{-4-2}{0+3}$

$m=\frac{-6}{3}=-2$

therefore

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2
