Answer:

15%

Step-by-step explanation:

Step 1: Count samples with one H

Why; Only 1 of 4 children in families are boys. The problem is simulated with samples.

Step 2: Count samples with only one H.

Why; The H represents the one boy in the family.

Step 3: Add the samples you counted with one H.

Answer: Your answer should be 3/20 after you change it into a percentage your final answer is 15%

The experimental probability that only 2 of 4 children in a family are boys is <u>50%</u>.

<h3>What is experimental probability?</h3>

Experimental probability refers to the chance of an expected success being achieved in a series of experiments conducted.

Experimental probability is the number of times that the expected success occurs as a fraction of the total number of times the experiment was conducted.

Like all probabilities, the experimental probability is based on the likelihood that what the experimenter expects is achieved.

Expected number of boys = 2

The number of children in the family = 4

Experimental probability = 50% (2/4 x 100)

Thus, we can conclude, based on the experimental probability, that <u>50%</u> (or 2) of the 4 children in the family are boys.

Answer:

Note that

Lower Bound = X - z(alpha/2) * s / sqrt(n)

Upper Bound = X + z(alpha/2) * s / sqrt(n)

where

alpha/2 = (1 - confidence level)/2 = 0.025

X = sample mean = 1723.4

z(alpha/2) = critical z for the confidence interval = 1.959963985

s = sample standard deviation = 89.55083319

n = sample size = 30

Thus,

Lower bound = 1691.355235

Upper bound = 1755.444765

Thus, the confidence interval is

( 1691.355235 , 1755.444765 ) [ANSWER]

*********************

We assumed taht the distirbution of these observations is approximately normally distributed.

*******************

Yes, because the values are not far away from each other.

Answer:

$\large\boxed{x=\dfrac{5}{4},\ y=\dfrac{15}{16}}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=\dfrac{3}{4}x&(1)\\\dfrac{5}{2}x+2y=5&(2)\end{array}\right\\\\\text{Substitute}\ (1)\ \text{to}\ (2):\\\\\dfrac{5}{2}x+2\left(\dfrac{3}{4}x\right)=5\\\\\dfrac{5}{2}x+\dfrac{3}{2}x=5\\\\\dfrac{5+3}{2}x=5\\\\\dfrac{8}{2}x=5\\\\4x=5\qquad\text{divide both sides by 4}\\\\x=\dfrac{5}{4}$
