A dairy scientist is testing a new feed additive. She chooses 13 cows at random from a large population. She randomly assigns no

ld = 8 to the old diet and nnew = 5 to a new diet including the additive. The cows are housed in 13 widely separated pens. After two weeks, she milks each cow and records the milk produced in pounds:
Old Diet: 43, 51, 44, 47, 38, 46, 40, 35
New Diet: 47, 75, 85, 100, 58
Let μnew and μold be the population mean milk productions for the new and old diets, respectively. She wishes to test
H0: μnew - μold = 0
Vs
HA: μnew - μold /= 0,
using α = 0.05.
(a) Graph the data as you see fit. Why did you choose the graph(s) that you did and what does it (do they) tell you?
(b) Choose a test appropriate for the hypotheses and justify your choice based on your answer to part (a). Then perform the test by computing a p-value, and making a reject or not reject decision. Do this without R and show your work. (Also do it with R, if you wish, to check your work). Finally, state your conclusion in the context of the problem.

What is the rate of change in decimal form for the points (1,5) (0,-3)
seraphim [82]

Answer:

The rate of change between (1, 5) and (0, -3) would be 8.0.

Step-by-step explanation:

"What is the rate of change between these two points" is the same as asking "what is the slope between these two points".

We are given the two points (1, 5) and (0, -3) and we are asked to find the rate of change (slope) between these two points. To do this, we could use the slope formula to find the rate of change between the two points. The slope formula is:

  • \frac{y_2-y_1}{x_2-x_1}

where (x₂, y₂) and (x₁, y₁) are the two points that we are trying to find the slope between.

Lets make (x₂, y₂) = (1, 5) and (x₁, y₁) = (0, -3). (It does not matter which is (x₂, y₂) and which is (x₁, y₁)). Now plug (x₂, y₂) = (1, 5) and (x₁, y₁) = (0, -3) into the equation:

\frac{5-(-3)}{1-0} =\frac{8}{1}=8

8 = 8.0, so the answer would be 8.0.

The rate of change between the two points would be 8.0.

I hope you find my answer helpful. :)
