Aresearcher has collected the results of a survey where the participants were asked how many hours of t. v. they watch each day. the researcher tallies the frequencies for each category and computes mean number of hours watched. she then creates a histogram to illustrate the overall distribution. which of the five steps of the statistical process did the researcher apply?
a. design the study
b. collect data
c. describe the data
d. make inferences

c. Describe the data

Step-by-step explanation:

Description of data involves the use of descriptive statistics to analyse/summarize a set of data (from samples) generated during a research.

Some of the process involved in the description of data involves the measure of central tendency ( averages, mean, median mode) and also measure of dispersion and graphing. Therefore, the case above described the data collected.

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'.
