For the given data above, calculate the f-ratio. Show ALL your
work
The basic idea in one-way ANOVA is to compare the variability
among the sample means to the variability within each sample. What
does variability among the sample means refer to? What does
variability within each sample refer to?
What do you think it means to say that a test is “statistically
significant”? How can saying this be used to strengthen inferences
drawn from such a test?
Can you think of an event that occurred in your personal or
professional life that required statistical significance? Share it
with your fellow students.
This assignment uses hypothesis testing to determine if there is
a significant difference between the means of three or more groups.
Find solutions to the following problems. Be sure to include a
statement about significance and complete a Tukey's HSD when
necessary.
Subjects were interviewed about their smoking habits in
cigarettes per day and were tested for their aerobic capacity.
Taking cigarettes per day as the explanatory (independent) variable
and aerobic capacity as the response (dependent) variable, find the
correlation...
Explain how multinationals can hedge transaction exposure using
forwards and options and explain any differences in using forwards
and options to hedge currency exposure. Do companies need to always
use derivatives such as forwards, futures and options to hedge
transaction exposure? If not, explain why not?
