A few years ago, it came as a surprise when Apple's iPhone 4 was found to have a problem. Users complained of weak reception, and sometimes even dropped calls, when they cradled the phone in their hands in a particular way. A survey at a local store found that 2% of iPhone 4 users experienced this reception problem. a. Determine whether the following statement is true or false. The population is all iPhone 4 users. multiple choice 1 True False b. Does 2% denote the population parameter or the sample statistic?

1. False.

2. Sample statistic

Step-by-step explanation:

1. The population in particular of the survey carried at a local store represents not the entire population of iPhone users, but of the selected sample of users only within the local store.

2. Remember, sample statistics refers to a part of a larger population selected in other fairly represent the whole population. Hence it logical to conclude that the 2% denote the sample statistics of those who experienced the reception problem.

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'.
