Question

You need to test a claim that more than 18% of students at your campus do not know their blood types. Which sampling method would you use? Where would you collect the sample? Describe how you plan to use the chosen sampling method to collect the data.

Answer 1

Answer:

Here the sampling technique to gather information is given as follows

i.e.,

Stratified Sapling Method as pursues:

Stage 1:

Acquire the Total number of understudies in the campus = N.

Stage 2:

Give Serial Numbers to every understudy arbitrarily beginning from 1 up to N covering all the N understudies of the grounds.

Stage 3:

Acquire the Sample Size = n by applying factual procedures.

Sep 4:

Characterize the whole grounds into m free non-covering divisions. Here we call every division as stratum.

Stage 5:

Depending up to the size of every one of the m strata ascertain these plentiful size so the aggregate of every one of these examples = n

Stage 6:

Through Random Sampling procedure, get the examples containing Serial quantities of understudies in every stratum.

Stage 7:

The accumulation of these tests, equaling all out n is the ideal example of understudies chose for the necessary overview.
