Answer: Sample IQR appears to be a biased estimator since it consistently underestimated the population IQR.
Step-by-step explanation: Checked by Khan Academy
Sample IQR appear to be a biased estimator of population IQR.
What is a biased estimator?
An estimate that deviates from the genuine population value is said to be biased. If the kind and extent of the bias are known, a biased sample may still be informative. When a sample's value matches the actual value of a population parameter, that is an unbiased estimator.
Matilda was curious if sample interquartile range (IQR) was an unbiased estimator of population IQR.
She placed ping pong balls numbered from 0 to 32 in a drum and mixed them well.
The IQR of the population is 16.
She then took a random sample of 5 balls and calculated the IQR of the sample.
She replaced the balls and repeated this process for a total of 50 trials. Her results are summarized in the dot plot below, where each dot represents the sample IQR from a sample of 5 balls.
Sample range appears to be a biased estimator since it consistently underestimated the population range.
The sample ranges appear to be centered below 32.
Therefore, the sample IQR is a biased estimator.

The point M is the midpoint of LN where M(-12, 6) and N (-2,-5).
What are the coordinates of point L?
Answer:
The coordinates of point L are:
(x₁, y₁) = (-22, 17)
Step-by-step explanation:
We know that the Midpoint Formula is given by:
[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
In our case:
M(-12, 6) is the midpoint. Thus,
(x, y) = (-12, 6)
N(-2, -5) is the second point, Thus,
(x₂, y₂) = (-2,-5)
We have to determine the coordinates of point L.
Let (x₁, y₁) be the coordinates of point L.
substituting (x, y) = (-12, 6), (x₂, y₂) = (-2,-5) in the Midpoint Formula
[tex]\left(-12,\:6\right)=\left(\frac{-2+x_1}{2},\:\:\frac{-5+y_1}{2}\right)[/tex]
Determining the x₁ coordinate of the point L
[tex]\frac{-2+x_1}{2}=-12[/tex]
[tex]-2+x_1=-24[/tex]
Add 2 to both sides
[tex]-2+x_1+2=-24+2[/tex]
Simplify
[tex]x_1=-22[/tex]
Determining the y₁ coordinate of the point L
[tex]\frac{-5+y_1}{2}=6[/tex]
[tex]-5+y_1=12[/tex]
Add 5 to both sides
[tex]-5+y_1+5=12+5[/tex]
Simplify
[tex]y_1=17\:\:\:[/tex]
Therefore, the coordinates of point L are:
(x₁, y₁) = (-22, 17)

Strands of copper wire from a manufacturer are analyzed for strength and conductivity. The results from 100 strands are as follows: Strength High Low High conductivity 74 8 Low conductivity 15 3 a. If a strand is randomly selected, what is the probability that its conductivity is high and its strength is high
Answer:
0.74
Step-by-step explanation:
Given :
__________________ STRENGTH __
__________________High _ Low
High conductivity _____ 74 __ 8
Low conductivity _____ 15 ___ 3
Probability that conductivity is high and strength is high :
This the probability of High conductivity n High strength = P(High conductivity n High strength)
Probability = required outcome / Total possible outcomes
Required outcome = P(High conductivity n High strength) = 74 (from table)
Total possible outcomes = total sample size = 100
Hence,
P(High conductivity n High strength) = 74 / 100 = 0.74

Find the product.
120 ×(0.002). It is 6th grade work don’t worry about where it says college
Answer:
0.24
Step-by-step explanation:
120 x 0.002 = 0.24
The correct answer is 0.24.
To find the product of 120 ×(0.002).
The zeroes are multiplied by the power of 10 which is 1/10 in particular.
For example.
The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that
1. N x 0.1 = N/0.1 < N
2. 1 x 0.5 = 0.5
3. 2 x 0.1 = 0.2
4. 100 x 0.55 = 55
120 ×(0.002) = 0.24.
Therefore, the 120 × 0.002 = 0.24

#3 (1 pt) A certain baseball card is very rare and is currently worth $2000. If the price of this card increases by 3% a year,
write an exponential equation for how much the card will be worth x years from now.
Answer:
$2000x(1.03)ˣ
Step-by-step explanation:
This is known as compound interest.
100% + 3% = 103%, so we put this into a decimal: 1.03
We now put this into the equation:
$2000x(1.03)ˣ
If you want to work out the price after, say 3 years, then you would change x to 3, so the equation becomes
$2000x(1.03)³
You can then use a calculator to work out the answer.
