The dot plot shows the number of hours that students spent watching TV. A dot plot titled hours students spend watching T V per week. The dot plot goes from 3 to 20 and is labeled hours. The data is as follows. 16 dots above 3, 13 dots above 4, 14 dots above 5, 2 dots above 6, 7, 8, 9, and 10, 8 dots above 11, 11 dots above 12 and 13, 3 dots above 14, 15, and 16, 0 dots above 17, 18, and 19, and 1 dot above 20. Select all the statements that are true. A typical student from this group spends more than 10 hours watching television each week. More students watch 3 hours of television than watch more than 3 hours of television. All students watch 20 or fewer hours of television each week. The most common answer for the number of hours that a student watches per week was 3. Some students do not watch any TV during the week.

The table below shows the function f. determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5]. a. 32 b. -32 c. 25 d. -25

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
