At least two girls means either 2, 3 ... or 8 girls.
Using the binomial law, we can write the probability in the form:
B(2,0.5)+B(3,05)+...+B(8,0.5)=

Continue simplifying:
Null hypothesis is stated as H0: Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.
Null hypothesis is defined as the hypothesis that stated that there is no relationship between the two population parameters. It is denoted by H0
To form the null hypothesis we take it as
Null hypothesis : The sample data provides no evidence to support some claim being made by an individual.
Thus according to the question the null hypothesis can be stated as
Null hypothesis, h0 : Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.

Answer:
1.1
Step-by-step explanation:
A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.
Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b
-2 = (3/4)*(12) + b
You'll get b= -11
So the equation of the parallel line intersecting the point given is y= 3/4x -11.
I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.
