Analyze the table representing five experiments with an increasing number of trials. The table shows the frequency of a coin landing heads up or tails up. A 4-column table with 5 rows. Column 1 is labeled Experiment with entries 1, 2, 3, 4, 5. Column 2 is labeled Trials with entries 20, 40, 60, 80, 100. Column 3 is labeled Heads with entries 12, 25, 20, 35, 48. Column 4 is labeled Tails with entries 8, 15, 40, 45, 52. What can you predict regarding the probability of the coin landing heads up? The frequency does not change with more trials. The experimental probability increases with more trials. With more trials, the frequency of heads up will equal the frequency of tails up. The frequency of heads up decreases with more trials.

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.
