A) The two line plots are attached.

B) In order to calculate the mean, you have to sum all the values and divide it by the number of values:
m(MSH) = (34 + 34 + 30 + 30 + 30 + 28 + 28 + 26) ÷ 8 
              = 240 ÷ 8
              = 30

m(RM) = (40 + 38 + 36 + 36 + 36 + 36 + 34 + 32) ÷ 8
           = 288 ÷ 8
           = 36

In order to calculate the mean absolute deviation (MAD), you need to calculate the absolute values from the mean, sum them up and divide it by the number of values; the absolute values of the difference from the mean are:
MSH = <span>{|34-30|, |34-30|, |30-30|, |30-30|, |30-30|, |28-30|, |28-30|, |26-30|}
        = </span>{4, 4, 0, 0, 0, 2, 2, 4<span>}

RM = </span><span>{|40-36|, |38-36|, |36-36|, |36-36|, |36-36|, |36-36|, |34-36|, |32-36|}
     = </span>{4, 2, 0, 0, 0, 0, 2, 4<span>}

Therefore,
MAD(MSH) = (</span>4 + 4 + 0 + 0 + 0 + 2 + 2 + 4) ÷ 8
                   = 16 ÷ 8
                   = 2

MAD(RM) = (4 + 2 + 0 + 0 + 0 + 0 + 2 + 4) ÷ 8
                = 12 ÷ 8
                = 1.5

C) In order to calculate the mean-to-MAD ratio, you need to simply divide the mean by the MAD:
r(MSH) = 30 ÷ 2 = 15

r(RM) = 36 ÷ 1.5 = 24

D) We can say that in Mount St Helens NVM elk antlers pairs are lighter but with a bigger variability (which means that they tend to be weight differently from each other), while in Rocky Mountain NP elk antlers pairs are heavier, but with less variability (which means that they tend to be similar to each other).

Could someone help me fast, ill mark as brainliest, and no links bc ill report you for that
Masteriza [31]
D is correct I believe since the values has an outlier it automatically gets rid of using mean. The dots are somewhat symmetrical. And for something to be skewed the dots are to be “connected”

How do you find the median?
Basile [38]

#1) Arrange the numbers from least to greatest.

#2) If there is a odd amount of numbers the middle number is your answer.

but if there is a even amount of numbers, take those two middle numbers, add them, then divide them by two. Then you got your answer.

A card is drawn at random from a standard deck of 52 playing cards. What is the probability that the card is either a king or a
Dafna11 [192]

Let’s count it.

I’m assuming that you have a regular deck of cards and that means 13 hearts and 13 kings.

You can pick any card of 52 with equal probability 1/52 for each.

So there are 52 opportunities of 1/52 probability to take any card from deck.

But you are looking only for 13 of hearts and for 13 of kings. That means your chance is (13 + 13) / 52 = 1/2  :)
