How is the rangeof a set of data different from a IQR

Suppose you're given a set of data. Arrange it in ascending order, from smallest to largest.

The "range" of this data can be thought of as "smallest to largest." Alternatively, you could subtract the smallest value from the largest and call that the "range" of the data set. That's it.

On the other hand, finding the IQR of a data set requires more work. Again, arrange the data in ascending order. Now identify the median as well as the first and third quartiles. Subtract the first quartile from the third quartile. The result is your IQR.

The tradeoff in doing more work to find the IQR is that the results tell us more about how the data set is distributed.

It is defined as the difference between the largest and smallest values in the middle 50% of a set of data. To compute an interquartile range using this definition, first remove observations from the lower quartile. Then, remove observations from the upper quartile.

Use the following problem to answer questions 8 and 9. A television manufacturer has three locations where it is finally assembl

Nonamiya [84]

Answer:

The probability of finding a non-defective television is 0.9815.

Step-by-step explanation:

We are given that a television manufacturer has three locations where it is finally assembled. Plants A, B, and C supply 65%, 15%, and 20% respectively of the televisions used by the manufacture.

Quality control has determined that 1.5% produced by Plant A are defective, while plants B and C have 2.5% defective products.

Let Probability that Plant A supply televisions = P(A) = 0.65

Probability that Plant B supply televisions = P(B) = 0.15

Probability that Plant C supply televisions = P(C) = 0.20

Also, let D = event that television is defective

Probability that television is defective given that it is supplied by Plant A = P(D/A) = 0.015

Probability that television is defective given that it is supplied by Plant B = P(D/B) = 0.025

Probability that television is defective given that it is supplied by Plant C = P(D/C) = 0.025

Now, to find the probability of finding a non-defective television firstly we will find the probability of a defective television.

Probability of a defective television is given by;

= P(A) $\times$ P(D/A) + P(B) $\times$ P(D/B) + P(C) $\times$ P(D/C)

= 0.65 $\times$ 0.015 + 0.15 $\times$ 0.025 + 0.20 $\times$ 0.025

= 0.00975 + 0.00375 + 0.005

= 0.0185

Now, probability of finding a non-defective television = 1 - Probability of a defective television

Probability of finding a non-defective television = 1 - 0.0185

= 0.9815

Therefore, the probability of finding a non-defective television is 98.15%.

How do i Evaluate this expression?

timofeeve [1]

$\text{Hey there!}$

$\bf{9.83+8.2(7.01)}$

$\text{You could solved this equation by doing PEMDAS}$

$\text{PEMDAS simply means}\downarrow$

$\text{Parentheses }$

$\text{Exponents}$

$\text{Multiplication}$

$\text{Division}$

$\text{Addition}$

$\text{Subtraction}$

$\text{In your equation you have \bf{MULTIPLICATION \& ADDITION}}$

$\text{Now, that we have every information we need.. lets solve the problem}$

$\text{We have to do \underline{MULITPLICATION} first then \underline{ADDITION} last}$

$\text{9.83 + 8.2(7.01)}$

$\text{8.2(7.01)=57.482}$

$\text{9.83 + 57.482 = 67.312}$

$\boxed{\boxed{\text{Thus your answer is most likely: \bf{67.312}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
