Answer:

IQR = 7

Step-by-step explanation:

To get the interquartile range of the set of data, the following steps must be followed:

Datas 4, 4, 6 , 7, 10 , 11 , 12, 14 ,15

Step 1: Rearrange the datas in ascending or descending order if not arranged.

4, 4, 6 7, 10, 11, 12, 14, 15

Step 2:

We will locate the (N+1/4)the cumulative value of the data where N is the total frequency of the data.

N = 4 + 4 + 6 + 7 + 10 + 11 + 12 + 14 + 15

N = 83

N+1/4 = 83+1/4

= 84/4

= 21st cumulative value

On cumulating the values up to the 21st value or more:

4 + 4 + 6 + 7

= 21

Since the 21st value falls on 7, then the interquartile range of the set of data is 7

Solve for m. 2= m/2 - 7 whats the answer?
xz_007 [3.2K]
Linear equations are all solved the same way. Figure out the operations performed on the variable. Undo those in reverse order.

Here, the variable is
- divided by 2
- has -7 added.

In reverse order, we undo these operations by
- adding 7
- multiplying by 2.

Whatever we do to one side of an equation, we must also do to the other side. That is how the equal sign remains valid.

2 = m/2 -7
2 +7 = m/2 -7 +7 . . . . . add 7
9 = m/2 . . . . . . . . . . . . simplify
2*9 = 2*m/2 . . . . . . . . multiply by 2
18 = m . . . . . . . . . . . . . simplify. (You know that 2/2 = 1, and m*1 = m.)

The answer is m = 18.

_____
Check:
.. 2 = 18/2 -7
.. 2 = 9 -7 . . . . . . . true. The answer checks OK.

Suppose that the probability of a baseball player getting a hit in an at-bat is 0.3089. If the player has 25 at-bats during a we
klio [65]

Answer:

P(X>9) = 0.3593

Step-by-step explanation:

Previous concepts  

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".  

Solution to the problem

Let X the random variable of interest, on this case we now that:

X \sim Binom(n=25, p=0.3089)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

For this case we want this probability:

P(X >9)

And we can use the complement rule like this:

P(X>9) = 1-P(X \leq 8)= 1-[P(X=0) + P(X=1) +....+P(X=8)]And we can find the individual probabilities like this:

P(X=0) =(25C0)(0.3089)^0 (1-0.3089)^{25-0} =0.0000974  

P(X=1) =(25C1)(0.3089)^1 (1-0.3089)^{25-1} =0.0011  

P(X=2) =(25C2)(0.3089)^2 (1-0.3089)^{25-2}=0.00584  

P(X=3) =(25C3)(0.3089)^3 (1-0.3089)^{25-3}= 0.02  

P(X=4) =(25C4)(0.3089)^4 (1-0.3089)^{25-4}=0.049  

P(X=5) =(25C5)(0.3089)^5 (1-0.3089)^{25-5}=0.092  

P(X=6)=(25C6) (0.3089)^6 (1-0.3089)^{25-6} = 0.138

P(X=7) =(25C7)(0.3089)^7 (1-0.3089)^{25-7}=0.167

P(X=8) =(25C8)(0.3089)^8 (1-0.3089)^{25-8}=0.168

And in order to do the operations we can use the following excel code:

"=1-BINOM.DIST(8,25,0.3089,TRUE)"  

And we got:

P(X>9) = 0.3593
