Choose an SRS of 1000 men from this population. Now what is the probability that x falls within ±2 mg/dL of μ? The larger sample

anyanavicka [17]

Answer:

(a) 0.5398

(b) 0.06376

Step-by-step explanation:

Given u=118, SD = 25, n = 10

Since we are dealing with a stratified random sampling (SRS)

We use,

Z = X - U/(Sd/√n).

The required probability =

Pr(112 < Z < 114)

Pr(112< Z< 114)=Pr( Z<114) - Pr(Z<112)

=Pr [Z<(114-118)/(25/√100)] - Pr[Z<(112-118)/(25/√100)]

= Pr(Z<-1.6) - PR(Z<-2.4)

= 0.5498 - 0.00820

= 0.5398

(b) Now since we are considering the whole population of 1000 men we use

Z = (X - U)/Sd

Now we the Probability of Pr(118±2)= Pr(120, 116)

= Pr(116 < X <120)

Pr(118±2) = Pr(Z<120-118/25) - Pr(Z<116-118/25)

Pr(118±2) = Pr(Z<0.08) - Pr(Z< -0.08)

= 0.53188 - 0.46812

Pr(118±2)= 0.06376

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of 100 men aged 20 to 34. Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ = 118 milligrams per deciliter (mg/dL) and standard deviation σ = 25 mg/dL.

(a) What is the probability that

¯¯¯

x takes a value between 114 and 122 mg/dL? This is the probability that

¯¯¯

x estimates μ within ±4 mg/dL.

(b) Choose an SRS of 1000 men from this population. Now what is the probability that

¯¯¯

x falls within ±4 mg/dL of μ? The larger sample is much more likely to give an accurate estimate of μ.

Order the subjects from least to greatest art for 25th English 13% math 0.28 other 7% science 21 over 100 social studies 0.15

Airida [17]

Answer:

Other, English, Social Studies, Art, Science, Math

Step-by-step explanation:

Let's start by tking each subject and putting them in decimal form, so that way we have an accurate way to see which is truly greater.

Art is 4/25, so to get the denominator up to 100 (the number it needs to be at to convert to decimal form). You have to times 25 by 4, and also 4 by 4. You get 16/100, which is .16 in decimal form.

English is 13%, or 13/100. Just convert it to decimal and you get .13

Math is already at .28

Other is at 7%, or 07/100. In decimal form, .07

Science is 21/100, and in decimal form, .21

Social studies is in decimal form at .15

You now have the numbers .16, .13, .28, .07, .21, and .15

Just put these in order and you get:

.07, .13, .15, .16, .21, .28

The length of the hypotenuse of the right triangle is 25 cm, the length of one of the legs is 10 cm. What is the length of the s

Anna007 [38]

Answer:

21 cm

Step-by-step explanation:

Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.

The right triangles formed by the altitude are all similar to the original. That means ...

AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant

Multiplying by AB and substituting the given numbers, we get ...

AD = AB²/AC = 10²/25

AD = 4

Then the segment DC is ...

DC = AC -AD = 25 -4

DC = 21 . . . . . centimeters
