A box contains six tickets labeled with numbers. The number on the tickets are -5, -4, -1, 3, 6, 9.

Required:
a. The expected value of the sample sum of the ticket labels in 5 independent random draws with replacement from the box is??
b. The standard error of the sample sum of the ticket labels in 5 independent random draws with replacement from the box is??
c. The expected value of the sample mean of the ticket labels in 5 independent random draws with replacement from the box is??
d. The standard error of the sample mean of the ticket labels in 5 independent random draws with replacement from the box is??
e. The expected value of the sample mean of the ticket labels in a simple random sample of 6 tickets from the box is??
f. The standard error of the sample mean of the ticket labels in a simple random sample of 6 tickets from the box is??

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
