Problem 1E

Each of the following processes involves sampling from a population. Define the population, and state whether it is tangible or conceptual.

a. A chemical process is run 15 times, and the yield is measured each time.

b. A pollster samples 1000 registered voters in a certain state and asks them which candidate they support for governor.

c. In a clinical trial to test a new drug that is designed to lower cholesterol, 100 people with high cholesterol levels are recruited to try the new drug.

d. Eight concrete specimens are constructed from a new formulation, and the compressive strength of each is measured.

e. Aquality engineer needs to estimate the percentage of bolts manufactured on a certain day that meet a strength specification. At 3:00 in the afternoon he samples the last 100 bolts to be manufactured.

Step-by-Step Solution:

Step 1 of 6:

Here for the given processes that involves sampling from a population, we have to define the population and then we have to state whether it is tangible or conceptual.

Population can be defined as the collection of all units or the  pool of units from which samples are drawn.

Tangible means something that can be felt by touch.

Conceptual means something that is based on some idea or some concept.

Step 2 of 6:

(a)

Here it  is given that a chemical process is run 15 times and the yield is measured each time.

The population here is the values of the yield measured each time.

Thus,this is tangible.

Step 3 of 6:

(b)

Here the population is group of all registered voters in a certain state.

This process is tangible since the pollster get the response in numbers.
