Idont understand this four students did a survey to find the soda flavor sixth-grade students prefer. the table below shows the method each student used to conduct the survey: student method trey asked 100 students at random from his seventh-grade class what their favorite soda flavor is jesse asked 100 sixth-grade students at random what their favorite soda flavor is nita asked 100 eighth-grade students at random what their favorite soda flavor is ruben asked 100 third-grade students at random what their favorite soda flavor is which student's survey is most likely not biased? trey jesse nita ruben (btw its not a.)

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.
