Answer:
A gatekeeper
Step-by-step explanation:
"60 Minutes" is acting as a gatekeeper.
Gatekeeping is a theory in mass communication that involves selecting, and then filtering items of media that can be consumed within the time or space that is allocated to an individual. This means gatekeeping falls into a role of surveillance and monitoring data. Information is filtered for dissemination, for the purpose of publication, broadcasting, the Internet, or some other mode of communication.
To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84
