A researcher has collected the following sample data. The mean of the sample below is 5.
abruzzese [7]

Answer:

The coefficient of variation is 72.66%

Step-by-step explanation:

Data : 3 , 5 , 12 , 3 , 2

We are given that The mean of the sample is 5.

Formula of standard deviation =\sigma = \sqrt{\frac{\sum(x-\bar{x})^2}{n}

Substitute the values :

\sigma = \sqrt{\frac{(3-5)^2+(5-5)^2+(12-5)^2+(3-5)^2+(2-5)^2}{5}}=3.633

Coefficient of variation=\frac{\sigma}{\mu} \times 100=\frac{3.633}{5} \times 100 =72.66\%

Hence The coefficient of variation is 72.66%

James has $120 in his savings account and plans to save 5x each month for 6 months. The expression 56x + 120 represents the tota
Kazeer [188]

Answer: Factorization of 6x + 120 = 6(x+20)

Factors = 6 and x+20

Step-by-step explanation:

Given: The expression 6x + 120 represents the total amount in the account after 6 months.

We need to factor the expression 6x + 120

We can write this as

6 x + 6 (20)

Common factor = 6 in both terms

So, 6 x + 6 (20) = 6(x+20)

Hence,  Factorization of 6x + 120 = 6(x+20)

The ages of the 32 recruits in police academy are normally distributed with a mean of 27 with a standard deviation of 2. What is
aksik [14]
Since it's a sample size, we use x, as the mean and s= standard deviation
            _
Given:  x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?

Let's calculate the Z score :
              _
         X - x              31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
           s                      2


Area (Z=2) =0.9772 , but Z ≥ 2  (at least) , then :
Area (Z≥2) = Area (Z≤ - 2)  = 0.0228

P(≥31)= 0.0228
