A windmill is used to generate direct current. Data are collected on 45 different days to determine the relationship between wind speed in mi/h \((x)\) and current in kA \((y)\). The data are presented in the following table.
a. Compute the least-squares line for predicting y from x. Make a plot of residuals versus fitted values.
b. Compute the least-squares line for predicting y from ln x. Make a plot of residuals versus fitted values.
c. Compute the least-squares line for predicting ln y from x. Make a plot of residuals versus fitted values.
d. Compute the least-squares line for predicting \(\sqrt {y}\) from x. Make a plot of residuals versus fitted values.
e. Which of the four models (a) through (d) fits best? Explain.
f. For the model that fits best, plot the residuals versus the order in which the observations were made. Do the residuals seem to vary with time?
g. Using the best model, predict the current when wind speed is 5.0 mi/h.

INTRODUCTION TO THEATRE THE PLAYWRIGHTS CRAFT There are a lot of disagreements and a lot of grey areas. When we privilege only written text we are ignoring 95% of all history (preliteratre) Essential Elements for Performance: IDEA PERFORMER AUDIENCE SPACE Playwright: The person responsible in theatre for creating the central idea and realizing it through plot, characters, and dialogue. SCRIPT: The written stage directions of a play and the dialogue spoken by characters that culminates in a story, incident, or event put into theatrical form. Necessary elements of a script: PLOT CHARACTER THOUGHT DICTION MUSIC SPECTACLE PLOT: the arrangement of actions in a play or dramatic text Three main plot structures: Climactic (also called intensive or masculine) Intensive: Starting action starts close to climax Masculine: Rising action leads up to a single climax, that occurs close to the beginning. Episodic (also called extensive or feminine) Series of episodes linked by theme, with own climax, don’t need to be chronological. Cyclic (also called patterned) Circle, came into being post ww2, because of the feeling of utility, holocaust and atomic bomb, nothing will change frustration, end the same way
