Consider the following data set:
3 -5 5 7 9 10 -3 35 2 1 1
a) Determine by hand (you can use the calculator) the mean,
median and mode of this data set. show enough details in your work
for it to be clear that you did this work.
b) Use MINITAB to obtain the above results for this data set
(and only these results).
c) By hand clearly determine the 5 number summary for this data
set and...
A = [4, 5, 9]
B = [-4, 5, -7]
C = [2, -7, -8, 5]
D = [1, -9, 5, -3]
E = [3, 3, -1]
Uz = 1/|z| ^z
d(X,Y) = (Rθ) d = diameter R = Radius θ = Theta
Find
a. Uc
b. d (D, C)
c. Let P = B + 3E, UP =
d. A x B
e. 3B x E
f. C x D

Enter the data in L1 and L2 in your TI calculator, find the
regression line, and construct a scatterplot with the regression
line included. Does a line appear to...
Matrix A2= [1 2 3; 4 5 6; 7 8 9; 3 2 4; 6 5 4; 9 8 7]
Note: TA2 is defined to be a linear transformation that maps
any vector x to A2* x. That is TA2 = A2*x. Also the range of the
Linear transformation represented by A2 is the same as the column
space of A2.
l) Find a basis for the null(TA2).
m) Find nullity of A2, TA2 and A2tA2.
n) Find rank(A2), rank(A2t),...

and the three-week Moving Average and evaluate the forecast
accuracy considering the Mean Absolute Error (MAE), Mean Squared
Error (MSE) and the Mean Absolute Percentage Error (MAPE) for each
of these two predictions. Compare both of them and determine which
is the best model
