Answer:

CASI

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

Sample survey questions are usually read from a computer screen. In a computer-aided personal interview (CAPI), the interviewer reads the questions and enters the responses. In a computer-aided self interview (CASI), the interviewer stands aside and the respondent reads the questions and enters responses. One method almost always shows a higher percent of subjects admitting use of illegal drugs.

This is because they get to interact with a computer rather than a human interviewer.

Ganezh [65]

Answer:

A)

Note that              

             

Lower Bound = X - z(alpha/2) * s / sqrt(n)              

Upper Bound = X + z(alpha/2) * s / sqrt(n)              

             

where              

alpha/2 = (1 - confidence level)/2 =    0.025          

X = sample mean =    1723.4          

z(alpha/2) = critical z for the confidence interval =    1.959963985          

s = sample standard deviation =    89.55083319          

n = sample size =    30          

             

Thus,              

             

Lower bound =    1691.355235          

Upper bound =    1755.444765          

             

Thus, the confidence interval is              

             

(   1691.355235   ,   1755.444765   ) [ANSWER]

How do I use substitution to solve
nekit [7.7K]
<span>The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.</span>
