A study was conducted to investigate the relationship between maternal smoking during pregnancy and the presence of congenital m

Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

$\mu=\pi=0.328$

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

$\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094$

B) The fraction with sample proportion of 0.45 or higher is

$z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714$

C) The fraction with sample proportion of 0.20 or lower is

$z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866$

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

$z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208$

What is the square root of 6 ?

Finger [1]

It's an irrational number ... it can never be written down on paper exactly.

The beginning of it is 2.449489... and it keeps going forever.

You might think that using only part of a number in a problem makes your
answer wrong. In a way that's true. But if you use 2.449489 for the square-
root of 6, then your final answer is only about 0.00003 percent wrong, and
that's close enough ... even if you're building bridges or spacecraft.

"But", you say, "How can I hand in an answer on my homework that's wrong ?"

Here's a secret that's so big that nobody ever talks about it. Once you know it,
it'll change your whole way of thinking. And you'll stop fishing for answers on
the internet:

The answers in homework don't matter ! The answer is the least important
part of any homework problem, and nobody needs it. If your teacher needed
an answer, then he/she could get it a lot faster by working out the problem.
If he/she didn't have time to work on it, then the teacher would go to somebody
who knows it cold ... they certainly wouldn't ask somebody who's just learning
it for the first time.

The purpose of the homework is NOT to generate answers. It's to lead you
down the path of learning how to do the problem. When somebody else gives
you the answer and you hand it in, 2 things happen:

#1: you cheat;
#2: you don't learn anything.

It's a bad deal all around.

PLZZZZ HELP!!!

quester [9]

Answer:

Expected Value= -$7
Bill should not play the game

Step-by-step explanation:

In the game, these are the payout:

30% of the time you will lose 20 dollars.
20% of the time you lose 40 dollars.
10% of the time you win 50 dollars
40% of the time you win 5 dollars.

To compute the expected value, take note that a loss is negative while a win is positive.

$E(X)=\sum_{i=1}x_1P(x_1)$

Therefore:

E(X)=(-20*0.3)+(-40*0.2)+(50*0.1)+(5*0.4)

E(X)=-7

The expected value of the event is -$7.
Based on the negative expectation, Bill should not play this game as he is expected to incur a loss.
