Acar's speedometer has a percent error of 5%. the speedometer currently shows that the car is traveling at a speed of 60 mph. which statement describes what the actual speed of the car could be? a. the actual speed of the car is either 30 mph or 90 mph. b. the actual speed of the car is either 55 mph or 65 mph. c. the actual speed of the car is either 57 mph or 63 mph. d. the actual speed of the car is either 58 mph or 62 mph.

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.
