State and use the average payoff strategy to choose the best
decision
State and use the aggressive strategy to choose the best
decision
State and use the conservative strategy to choose the best
decision
State and use the opportunity loss strategy to make the best
decision
Suppose the decision maker obtains information that enables the
following probabilities assessments: P(s_1) = 0.5; P(s_2) = 0.2;
P(s_3) = 0.2; and P (s_4) = 0.1. use the expected value approach to
determine the optimal strategy
Use the sample space (5, 6, 7, 8, 9, 10, 11, 12, 13, 14) to find
the probability for a random selected
a) P(integer)
b) P(less than 10 | less than 13)
c) P(greater than 8 | less than 11)
d) P(greater than 7 | greater 12)

The table below lists the frequency of wins for different post
positions in the Kentucky Derby horse race.
Use a 0.05 significance level to test the claim that the
likelihood of winning is the same for the different post
positions.
What is the critical value (the X2 value)? [Round to the nearest
thousandths place]

Above we have the final averages of the last stats and I want to
know if the class average falls within the boundaries of all my
statistics classes for the past 20 years.

We need to find the confidence interval for the SHOE SIZE
variable. To do this, we need to find the mean and standard
deviation with the Week 1 spreadsheet. Then we can the Week 5
spreadsheet to find the confidence interval. This does...

a) draw the scatter plot and draw the line of best fit
b) Calculate and interpret the correlation between promotional
expenses and sales
C) Calculate the regression equation( calculate the slope and
intercept of the regression line
d)Interpret the slop coefficient of regression equation
e)Using the regression equation calculate the sales volume with
respect to promotional expense of 4.
f) Obtain the coefficient...
