You need to test a claim that more than 18% of students at your campus do not know their blood types. Which sampling method woul
DerKrebs [107]

Given that:

p = 18\% ---- i.e. the proportions that do not know their blood group

There are several sampling methods, however the best sampling method to use in this case is a simple random sampling.

This is because it gives each student in the campus an equal chance of being selected to participate.

The sample would be collected from the population of students in the school campus.

From the question, given proportion is about the students in the campus. So, the sample to be selected must represent the case study, which are the students

The chosen sample would be used by conducting a test of hypothesis

To carry out this test, we need to set the null and alternate hypotheses.

Then calculate the critical value.

Then the test statistic.

How the test statistic compares to the critical value will determine if the null hypothesis will be accepted or rejected

Please help! What is the function for the graph
Evgen [1.6K]

When x = 0 the value of the function is 2 so its either A or B.

When x = 1, y = 8 so substituting these values in A we get:-

8 = 2 * 8^1 = 16 so

its Not A. Try B:-

8 = 2 *4^1 = 8 which fits

Answer is choice B

Write the equation of a line that is parallel to {y=-\dfrac{5}{4}x+7}y=− 4 5 ​ x+7y, equals, minus, start fraction, 5, divided b
AlladinOne [14]

Write the equation of a line that is parallel to y=-5/4x + 7

Any line parallel to the given line will have the same slope. In an equation presented in the y-intercept form, the slope is always the coefficient of "x". In this case, the slope is -5/4 (meaning the next point is down 5, and 4 to the right).


Our equation so far looks like this: y = -5/4x + b

"b" represents the y-intercept. To solve for be, we will need to substitute values into x and y. The next piece of information it gives us is one of the points, or solutions, of the line. This means that since this point is on the line, we can use its x and y values to substitute.


x = -4

y= 1

y = -5/4x + b

1 = -5/4(-4) + b

1 = 5 + b

-4 = b


Final Answer: y = -(5/4)x -4

How can I write a story about the doubles plus 2 fact 5+7=12.??
aksik [14]
One <u>possible story</u> is:

I had 5 apples.  My sister gave me 7, and now I have 12.

Explanation:

We are writing a story for 5+7=12.  This means we need to start with 5 objects and somehow gain 7 more.  In our story, we start with 5 apples and we get 7 more.

The last part is that our total must be 12.  In our story, we end with 12 apples.
