A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34.

Answer:

The sampling distribution of x is N(118, 2.5).

Step-by-step explanation:

We have that:

The mean of the population is $\mu = 118$

The standard deviation of the population is $\sigma = 25$ .

(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.)

The mean of the sampling distribution is the same as the mean of the population.

The standard deviation of the sampling distribution is the standard deviation of the population divided by the square root of the sample size. So

$s = \frac{25}{\sqrt{100}} = 2.5$

This means that the sampling distribution of x is N(118, 2.5).

What is 6b-27=3(5b-2)

irga5000 [103]

Hi,

Start with 6b-27=3(5b-2)

then add 27 to each side, 6b-27+27=15b-6+27

next simplify, 6b=15b+21

now subtract 15b from both sides, 6b-15b=15b+21-15b

simplify again, -9b=21

divide both sides by -9, -9b/-9 = 21/-9

answer: -7/3

Have a great day!

How do is do this problem 1/3(x+6)=1/2(x-3)

xz_007 [3.2K]

Answer:

Your solution is 21 = x.

Step-by-step explanation:

This problem involves two fractions. The LCD is 6. Mult. both sides of this equation by 6 to obtain 2(x+6) = 3(x-3).

Performing the indicated multiplication, we get 2x + 12 = 3x - 9.

Combining like terms: 21 = x
