Test the hypothesis that Love Makes The World Go Round, and report your results at the 5% significance level. What is the power of your test? In your answer, you should refer to Yahweh, Allah, Buddha, Vishnu or Kibo as you deem appropriate. Give confidence levels. QUESTION 2 [multivariate analysis] The file asciisword.dat contains 187 ASCII swords extracted from various .sigs over the past five years. Perform a principal components analysis, a factor analysis, a cluster analysis, a correspondence analysis, and an autopsy on this data. Is there any evidence that the average sword size has grown over the period in question? Find the correlation between ASCII swords and Perth. QUESTION 3 [time series] Perform a spectral analysis on the United States of America. What proportion of total variation can be accounted for by frequencies below 100 cycles per unit time? For estimating the spectrum, you should use the Parzen and Tukey windows. For extra credit, you can use the Microsoft and X windows, although this is not necessary. QUESTION 4 [graphical presentation] The following plot is of average household income, adjusted for inflation and interest rates, versus the price of housing units on Venus. ************* ******,.';.,.;',';.****** ****';.,.;'';.<>:":><.;';.,>;**** **';.,.;':><>:";.,.;':><>:":.,.;';.** *';.,.;';.,,,,.;":><>:":><>:";.,.;';.,* *';.,.:":><>:";.,.;| |';.,>:":><>:';.,,* **';.,.;';.,.;;*| :|' |||*';.,..":><>:;** ***';.,.;':><;* || ||.| | *';.,.;';.,;*** **":.,.;'":* |>|| || | *.,.;.,.;;** ***;.,.;** || | ||| **:><>:*** ****** | |||| | ****** |||| | | | ||||| || | | | || | | | || | | | | | || | ||| | ||| | | || | .*#|| || |||#*. .*#@@| || || |@@#*. -------------------------------------------------------------- What is wrong with this plot? Suggest ways of improving it, bearing in mind the target audience's penchant for wearing tinfoil hats. QUESTION 5 [nonparametrics] Using robust nonparametric methods, test the hypothesis that TIME=MASS. Does the choice of units have any bearing on your result? Estimate the gravitational permeability of free space, and compare this to the temporal permeability of free space (a constant at 5.34538*pi Abians per cubic meter). Does the concept of free space make sense in a social Darwinist context? Estimate the gravitational permeability of rented space. What do your results imply for low-income earners and Republican election hopes in 1996? QUESTION 6 [epidemiology] Using appropriate epidemiological methods, estimate the relative risk. Why is it so? Using appropriate epistemological methods, answer this question. What does "42" have to do with anything?
