Given that:
---- 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

Amazing good job you did great
485, because the mean means you need to calculate the average. to find the average, you take the smallest number from the data set and the largest number. add the largest number by the smallest number and divide by the set of numbers you added (2). Example: (720+250=970 divided by 2 =485)
Answer:
You input the equation they give you into the table to get an outcome. The Equation they gave you is x=y. simply, what ever X is, thats what y is. x=y. On the table it says that X is 3. If x is 3 then y is three because they are equal. if X is 7 then Y is 7. its the same throughout the whole table. To write it as an ordered pair you write (X,Y) if x is three y is three so the ordered pair would look like (3,3)
