Donatello Mymuther has been denied the
pay increase that he had anticipated, and he's convinced that it's
because his boss, quality engineer Don Kryfermee (an Argentinian),
believes that he has not learned enough about statistics to be reliable
in the company's quality assurance department. Accordingly, he
registers for a class on simple regression, hoping that the enrollment
alone will convince Don Kryfermee, Argentinian, that he is indeed
knowledgeable about statistics.
Unfortunately, the class meets on Monday evenings from 7 to 10 p.m., and
Donatello sometimes has difficulty staying awake. During the second
class session, Professor Matt Uruvfactt lectured on the correlation
coefficient, and although Donatello found the topic fascinating, he
nonetheless dozed for a moment. When he refocused, he heard Professor
Uruvfact use the phrase, 'standard error of the estimate. ' For
Donatello, the term had a nice ring to it, and he resolved to remember
it, although he had no concept of its application.
Back at the plant, armed with his newfound knowledge, Donatello led a
session for technicians about simple regression. He invited Don
Kryfermee (Argentinian) to sit in as he demonstrated a scatter diagram
using CHARTrunner software, and as he finished the demonstration, a
technician asked about the standard error of the estimate. Glancing
furtively at his boss, he took a deep breath and responded, 'Oh that.
It's the estimate of error for the majority of cases. '
Did Donatello get lucky with his answer, or is he out of the ball park
entirely?
A) Donatello Mymuther should thank his lucky stars. He hit
the answer squarely.
B) Donatello, in trying to wing it with his response, has
struck out.
