Determine whether the results appear to have statistical​ significance, and also determine whether the results appear to have pr

actical significance.In a study of a gender selection method used to increase the likelihood of a baby being born a​ girl, 1971 users of the method gave birth to 965 boys and 1006 girls. There is about an 18​% chance of getting that many girls if the method had no effect.
Because there is a 18% chance of getting that many girls by?

Answer:

(B) does not have statistical significance

Step-by-step explanation:

given data

gave birth = 1971

boys = 965

girls = 1006

solution

we know here that there is a 18% chance of getting that many girls by chance

as  method it is (B) does not have statistical significance

because here By this method

Percentage of girls is = \frac{1006}{1971}

percentage = 51.04 %

the ratio of boys to girls in a class is 5:4 there are 36 students in the class how many students are girls
Alina [70]
First add up the total parts in the ratio.
5 + 4 = 9
Now we need to know the value of each part
36 / 9 = 4
The girls has total of 4 parts, therefore we can just multiply the number of parts by the amount in each part
4 x 4 = 16
So there r 16 girls in the class

What is the value of the smallest of five consecutive integers if the least minus twice the greates equals -3
Alexeev081 [22]

Answer: (b)

Step-by-step explanation:

Given

There are five consecutive integers and the least minus twice the greatest equals to -3

Suppose x,x+1,x+2,x+3,x+4 are the five consecutive integers

According to the question

\Rightarrow x-2(x+4)=-3\\\Rightarrow x-2x-8=-3\\\Rightarrow -x=8-3\\\Rightarrow x=-5

option (b) is correct.

Graph the points (-3,4) and (1,1). If you drew a line through the points, name three other points that would be on the line. How
Andrej [43]
The easiest way to solve this problem is to find the equation of the line joining these two points, then get the values of the points on this line.

We have first point (x1,y1) = (-3,4) and second point (x2,y2) = (1,1).
The equation of the line is y = mx + c
The slope (m) = (y2-y1) / (x2-x1) = (1-4) / (1--3) = -0.75

Then we will use one of these points to get the value of c as follows:
y = mx + c
1 = -0.75 (1) + c ..............> c = 1.75

The equation of this straight line is:
y = -0.75 x + 1.75

Now to get points on this line, we will assume values for either x or y and calculate the other as follows:
1- For x = 0:
y = -0.75 (0) + 1.75 = 1.75
point is (0,1.75)
2- For y = 0:
0 = -0.75 x + 1.75 ..............> x = 2.334
point is (2.334,0)
3- For x = 2:
y = -0.75(2) + 1.75 = 0.25
point is (2,0.25)
