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

The table represents the function f (x) = 3x-1
Ann [662]

Answer:

a=-16, b=11, c=23

Step-by-step explanation:

The function whose table is drawn is

f(x) = 3x - 1

To find the value of a, we substitute x=-5.

f( - 5) = 3( - 5)  - 1  \\ f( - 5) =  - 15 - 1 \\ f( - 5) =  - 16

\therefore \: a =  - 16

To find the value of b, we substitute x=4.

f(4) =3(4)  - 1  \\ f(4) = 12 - 1 \\ f(4) =  11

To find the value of c, we substitute x=8,

f(8) = 3(8) - 1 \\ f(8) = 24 - 1 \\ f(8) = 23

c = 23

What is the value of (f • g)(2)?
Alona [7]

Answer:

f(g(2)) = 1

Step-by-step explanation:

Another way to write this composite is f(g(2)).  We first have to compute g(2), then fit that value into f.  

g(2)=2^2=4.

g(2) = 4.  Now we have to find f(4):

f(4) = 4 - 3 = 1
