Mice and Pain Can you tell if a mouse is in pain by looking at its facial expression? A new study believes you can. The study1 c
kotykmax [81]

<u>Explanation:</u>

1. a) Null hypothesis: There is <em>no</em> statistically significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

b) Alternate hypothesis: There is a statistically-significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

2. Yes, because a statistically significant data implies that there is sufficient evidence to believe the study, based on the results of the findings.

3. No, since the variables are different in this case. Here we are dealing with a non-painful solution so there may be no sample correlation as extreme as that found in the original study.

4. Possibly, because every hypothesis is an assumption until it is proven. Thus, in every statistical research, there may be different findings.

Solve the following proportion for 17/13=9/u
ValentinkaMS [17]

Answer:

<h2>u = 6.88</h2>

Solution,

\frac{17}{13}  =  \frac{9}{u}

Sinplify the equation using cross multiplication

17 \times u = 13 \times 9

Calculate the product

17u = 117

Divide both sides of the equation by 17

\frac{17u}{17}  =  \frac{117}{17}

Calculate

u = 6.88

Hope this helps...

Good luck on your assignment..

£620 is divided between Malachy, Paul &amp; Brian so that Malachy gets twice as much as Paul, and Paul gets three times as much
geniusboy [140]

Answer: Paul gets £186

Step-by-step explanation:

Paul has 1/2 as much as Malachy, and Brian has 1/3 as much Paul, therefore Brian has 1/6 as much as Malachy.

1/2 * 1/3 = 1/6

So Malachy’s amount equals 1 in this equation, Paul’s amount equals 1/2 in this equation, and Brian’s amount equals 1/6 in this equation.

1 + 1/2 + 1/6 = 1 + 3/6 + 1/6 = 1 4/6

Now, divide 620 by 1 4/6 to find Malachy’s amount.

620/1 4/6 = 372

Now, divde 372 by 2 to get Paul’s amount.

372/2 = 186
