Answer:

$m = \dfrac{3}{4}$

Step-by-step explanation:

We would like to find the <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u> of the line of the given equation .

$\longrightarrow y =\dfrac{3}{4}x -1$

We know that <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>i</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u><u> </u><u>f</u><u>o</u><u>r</u><u>m</u><u> </u> of the line is given by ,

$\longrightarrow y = mx + c$

where ,

m is the slope
c is y intercept

Now we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

$\longrightarrow \underline{\underline{m=\dfrac{3}{4}}}$

Hence <u>o</u><u>p</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>C</u><u> </u> is correct choice .

Levart [38]

Answer:

a. 5.26

Step-by-step explanation:

As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.

t score=Xbar A- Xbar B/Sd of difference of means

t score=55-51/0.76

t score=4/0.76=5.26
