Hello there! you can use the expression !
To find slope, subtract the y values over the x values.
In this case:
2 - - 1 / - 3 - 7
3 / -10
So, -3/10 would be the slope of these points.
Hope this helps, have a great day!

Answer: 1 ⁸/₂₁ litres
Step-by-step explanation:
First find a common multiple to enable you add them up:
= 21
21 will be the denominator.
Multiply each numerator by the number you get when you divide 21 by the denominator.
= 21/3 = 7
= 7 * 2 = 14
= 21/7 = 3
= 3 * 5
= 15

Answer:
(1) Correct option is B.
(2) Correct option is C.
Step-by-step explanation:
The information provided is:
The (1 - <em>α</em>)% confidence interval for the difference between two mean is:
The critical value of <em>t</em> is:
degrees of freedom
Compute the 95% confidence interval for the difference between two mean as follows:
Thus, the 95% confidence interval, (2.14, 3.86) implies that the true mean difference value is contained in this interval with probability 0.95.
Correct option is B.
The null value of the difference between means is 0.
As the value 0 is not in the interval this implies that there is a difference between the two means, concluding that priming does have an effect on scores.
Correct option is C.
