Answer:
C. -0.34
Step-by-step explanation:
We have that for a normal distribution, the value of z can be calculated using the following formula:
z = (x - m) / sd
where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 16.3, m = 17.4 and sd = 3.2
if we replace we have:
z = (16.3 - 17.4) /3.2
z = -0.3437
if we round to 2 decimal places, it would be -0.34, that is, the answer is C.
Answer:
Advantages:
- It is easier for people to choose an option rather than to write an essay. The questionnaire reflects what the person is thinking and what the person's point of view is, which as a result makes it easier to analyze and conclude results
- A wide range of questions can be asked within one questionnaire, which makes it an effective way to conduct a survey/test
