14. A researcher conducted a medical study to investigate whether taking a low-dose aspirin reduces the
chance of developing colon cancer. As part of the study, 500 adult volunteers were randomly assigned
to one of two groups. Half of the volunteers were assigned to the experimental group that took the a low-
dose aspirin each day, and the other half were assigned to the control group that took a placebo each
day. At the end of six years, 16 of the people who took the low-dose aspirin had developed colon
cancer and 26 of the people who took the placebo had developed colon cancer. At the significance
level a 0.05, do the data provide convincing statistical evidence that taking a low-dose aspirin each
day would reduce the chance of developing colon cancer among all people similar to the volunteers?

can you hlep me do homework?

step-by-step explanation:

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'.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
