Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. Thi
Dovator [93]

Complete question:

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby this mention is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect so the probability of a girl is 0.5. Assume that the group consists of 36 couples.

A) Find the mean and standard deviation for the number of girls in groups of 36 births.

B) Use the range rule of thumb to find the values separating results that are significantly low and significantly high.

C) Is the result of 33 girls significantly high? A result of 33 girls would suggest the method is effective or is not effective?

Answer:

a) mean = 18

Standard deviation =3

b) low range = 12

High range = 24

c) The result of 33 girls is significantly high. Yes, the method is effective.

Step-by-step explanation:

Given:

p = 0.5

n = 36

a) The mean is the product of n and p

Mean u = np

u = 36 * 0.5 = 18

The standard deviation is the square root of the product of n and p&q.

S.d ó = \sqrt{npq}

= \sqrt{np(1-p)}

= \sqrt{36(0.5)(1-0.5)} = \sqrt{9} = 3

b) To find the range rule of thumb:

• For low range

Low range = u - 2ó

= 18 - (2 * 3)

= 12

• High range

= u + 2ó

= 18 + (2*3)

= 24

c) The result is significantly high, because 33 is greater than 24 girls.

A result of 33 girls would prove the method as effective.

The number from standard form to decimal form is as follows:

2.077  ×  10⁻⁴ = 0.0002077

<h3>How to express number in standard form?</h3>

Standard form is a convenient way of writing very large or very small numbers.

Standard form is a way of writing a number so it is easier to read.

Standard form is like scientific notation and is typically used in science.

Standard form is like scientific notation and it is represented in the format as follows:

a × 10ᵇ

Therefore, the number is already in standard form but we can convert it back to decimal form as follows:

2.077  ×  10⁻⁴ = 2.077 × 1 / 10000 = 0.0002077

Solve for x. 3x/2 = 15
defon

3x : 2 = 15

3x = 15 * 2

3x = 30

x = 30 : 3

x = 10

--------------------------------

3(10)  :2 = 15
