Let's go through each answer, using the line plot for reference.

A.
This is incorrect, because the boys' line plot has a few on 1, 2, 3, and it has one on 6, which makes it more spread out than the girls'.

B.
This is correct because if you find the mean/average from both data sets, you'll see the boys' is higher. (and also the girls' have more on 0 than the boys, so it's kind of obvious.) :)

The answer is B.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Answer:

Following are the solution to the given question:

Step-by-step explanation:

$H_0:$ Management quality and corporate reputation are independent.

$H_1:$ Management quality and corporate reputation are not independent.

Test statistic:

$\to \chi^2 = \frac{\sum (O-E)^2}{E}$

$= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333 +0+3.2143+7.5\\\\= 17.02806$

The critical $\chi^2$ for $df = (r-1)(c-1) = (3-1)(3-1)= 4$ and $\alpha = 0.05$ is $\chi^2= 9.4877$

Test statistic:

$17.02806 > 9.4877$ therefore rejecting the null hypothesis $H_0$ .

p-value $= 0.001909$

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

phenytoin comes from the pharmacy as an IV solution of 1000mg/250ml. a loading dose of 700 mg has been ordered. how many millime

Vedmedyk [2.9K]

We can write the following proportion between the milligram and milliliters:

$1000\div 250 = 700\div x$

Solving for x, we have

$x=\dfrac{250\cdot 700}{1000}=175$

Intuitively, the original 1000mg/250ml solution tells us that the number of milliliters is one fourth of the number of milligrams.

So, if we want 700mg, we have one fourth of this value for the milliliters:

$\dfrac{700}{4}=175$

"We keep tossing a fair coin n = 10^6 million times, write down the outcomes: it gives a Heads-and-Tails-sequence of length n. W

anyanavicka [17]

Answer:

Check the explanation

Step-by-step explanation:

Let $X_{i}$ be the indicator random variable that takes the value 1 if the ith coin is the first coin in a sequence of 19 consecutive heads.

For any sequence of length 19, the starting coin can be from toss i ,

such that i is between 1 and n - 19+1

Thus the number of such sequences is

Step-by-step explanation:

For f(x) to be odd then f(- x) = - f(x)

determine whether

9 - 4(- x)² is equivalent to - (9 - 4x²) → C
