The median is a better measure of center for the male's data, while the mean is a better for the female's data.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

(a) The IQR of the male's data

From the given male's boxplot, we have the following data elements;

Upper quartile (Q3) = 14

Lower quartile (Q1) = 2

Then the IQR is calculated as:

IQR = Q3 - Q1

So, we have:

IQR = 14 - 2

IQR = 12

Hence, the IQR for the given males' data is 12

(b) The difference between the median values can be calculated as;

Median of male's data = 14

Median of female's data = 9

The difference (d) between the median values is;

d = 14 - 9

d = 5

Hence, the difference between the median values of each data set is 5

(c) The distribution of data

It is found that the median is a better measure of center for the male's data, while the mean is a better measure of center for the female's data.

Step-by-step explanation:

There is a 96.37% probability that the company will find 2 or more defective products.

There is a 2.08% probability that the company will find 4 or more defective products.

There is a 0.02% probability that the company will find 5 or more defective products. So company will give profit.

There are only two possible outcomes for each product: either it is defective or it is not. The binomial distribution is used to answer this question because each product's defect probability is independent of all other products.

Binomial probability distribution

The probability of precisely x successes on n repeated trials is known as the binomial probability.

[tex]P_x = \;^nC_r.p^x.q^{n-x}[/tex]

Where,

Px = binomial probability,

 [tex]\;^nC_r =[/tex] number of combination

p = probability of success on a single trial

q = probability of failure on a single trial = (1 - p)

n = number of trials

x = number of times for a specific outcome within n trials

So, from question,

1) The probability that, 2 or fewer defective products is;

P(X≤2) = P(X=0) +  P(X=1)+ P(X=2) -----------------(1)

So,

[tex]P_x = \;^nC_r.p^x.q^{n-x}[/tex]

P(X=0) = [tex]\;^{20}C_0.p^0.q^{20-0}[/tex] =  [tex]\; 1.(1-p)^{20-0}[/tex] = (1-0.037)²⁰ = (0.963)²⁰ =  0.4704

P(X=1) = [tex]\;^{20}C_1.p^1.q^{20-1}[/tex] =  [tex]\; 20.(0.037).(0.963)^{19}[/tex]  = 0.3614

P(X=2) = [tex]\;^{20}C_2.p^2.q^{20-2}[/tex] =  [tex]\;190\times(0.037)^2\times(0.963)^{18}[/tex] = 0.1319

Now, putting the all values in equation (1)

P(X≤2) = P(X=0) +  P(X=1)+ P(X=2) -----------------(1)

           = 0.4704 + 0.3614 + 0.1319

P(X≤2) = 0.9637 = 96.37%

There is a 96.37% probability that the company will find 2 or more defective products.

2)

1.23% are defective means p = 0.0123

The probability that find 4 or more defective products are;

 P(X≤4) = 1 - P(X< 4) -----------(2)

 P(X< 4) = P(X=0) + P(X=1)+ P(X=2) + P(X=3)-----------------(3)

So,

P(X=0) =  = [tex]\;^{20}C_0.p^0.q^{20-0}[/tex] =  [tex]\; (0.9877)^{20}[/tex] = 0.7807

P(X=1) = [tex]\;^{20}C_1.p^1.(1-p)^{20-1}[/tex] =  [tex]20\times (0.0123)\times (0.9877)^{19}[/tex] = 0.1944

P(X=2) = [tex]\;^{20}C_2.p^2.(1-p)^{20-2}[/tex] =  [tex]190\times (0.0123)^2\times (0.9877)^{18}[/tex] = 0.0024

P(X=3) = [tex]\;^{20}C_3.p^3.(1-p)^{20-3}[/tex] =  [tex]1140\times (0.0123)^3\times (0.9877)^{18}[/tex] = 0.0017

So,

P(X< 4) = 0.7807+0.1944+0.0024+0.0017 =0.9792

 P(X≤4) = 1 - P(X< 4) = 1 - 0.9792 = 0.0208 = 2.08%

There is a 2.08% probability that the company will find 4 or more defective products.

3)

1.28% are defective means p = 0.0128

The probability that find 5 or more defective products are;

 P(X≤5) = 1 - P(X< 5) -----------(4)

 P(X< 5) = P(X=0) + P(X=1)+ P(X=2) + P(X=3)+ P(X=4)-----------------(5)

So,

P(X=0) =  = [tex]\;^{20}C_0.p^0.q^{20-0}[/tex] =  [tex]\; (0.9872)^{20}[/tex] = 0.7728

P(X=1) = [tex]\;^{20}C_1.p^1.(1-p)^{20-1}[/tex] =  [tex]20\times (0.0128)\times (0.9872)^{19}[/tex] = 0.2004

P(X=2) = [tex]\;^{20}C_2.p^2.(1-p)^{20-2}[/tex] =  [tex]190\times (0.0128)^2\times (0.9872)^{18}[/tex] = 0.0246

P(X=3) = [tex]\;^{20}C_3.p^3.(1-p)^{20-3}[/tex] =  [tex]1140\times (0.0128)^3\times (0.9872)^{18}[/tex] = 0.0019

P(X=4) = [tex]\;^{20}C_4.p^4.(1-p)^{20-4}[/tex] =  [tex]4845 \times (0.0128)^3\times (0.9872)^{18}[/tex] = 0.0001

So,

  P(X< 5) = 0.7728+0.2004+0.0246+0.0019+0.0001 = 0.9998

  P(X≤5) = 1 - P(X< 5) = 1 - 0.9998 = 0.0002 = 0.02%

There is a 0.02% probability that the company will find 5 or more defective products. So company will give profit.

I am not sure if the polygon is drawn on a coordinate plane.  I cannot see any horizontal or vertical lines to tell you exactly how many units to move up.

The interval in which the function has positive average rate of change is x > √3

The function is given as

f(x) = x^3 - 9x

Differentiate the above function to determine the average rate of change

So, we have

f'(x) = 3x^2 - 9

Set the function to greater than 0

So, we have

3x^2 - 9 > 0

Add 9 to both sides

3x^2 > 9

Divide by 3

x^2 > 3

Take the square root of both sides

x > √3

Hence, the interval in which the function has positive average rate of change is x > √3

Mathematics shaping the modern world.

The slope of  P=(-4,-1) Q=(-3,-3) is -2.

Given,

 P=(-4,-1)

Q=(-3,-3)

The  slope  between two points   P=(x₁, y₁)

Q=(x₂ ,y₂)

slope = (y₂-y₁)/(x₂-x₁)

So slope between  P=(-4,-1)   Q=(-3,-3) is

 [(-3)-(-1) ]/ [(-3)-(-4)]

=-2/1

=-2

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line may be used to compute the slope of any line. The ratio of "vertical change" to "horizontal change" between two separate locations on a line is calculated using the slope of a line formula.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Finding the slope between two separate locations and calculating the slope of a line are related tasks. In general, we require the values of any two separate coordinates of a line in order to determine its slope.
