As shown below are two normal curves. Let and o be the mean and the standard deviationof curve A (the more peaked curve) and Hg and og be the mean and the standard deviation ofcurve B (the broader curve). What do you observe about these two normal curves?P(x)0.4A0.30.20.10.02 4 6102 14Select one:a. All statements are true.b. The mean of both curves is 8. Symbolically, HA = HB = 8.c. Both curves are symmetric with respect to their means.O d. Curve A has a lower standard deviation than Curve B. Symbolically, oA8.

The lower standard deviation means that the values are closer to mean or that the data is not wide spread, while the higher standard deviation implies that the values of the data set are quite far away from the mean or that the data is wide spread. More peaked curve implies that values are closer to the central value (mean) and a flatter curve implies that values are not closer to the mean of the data. The curves shown in the graph are both symmetric as they appear to be bell-shaped curves and have same mean i.e 8 but curve A is more peaked than curve B indicating that standard deviation for Curve A is less than that of Curve B. Answer : a. All statements are true.

Which of the following statements is not true? There is only one median for each variable. One definition of the median states that, for an odd number of observations, the median is the middle score when scores are placed in order of magnitude. Another term for the median is 50th percentile. The median is generally more sensitive to (i.e., affected by) the presence of a few extreme observations than is the mean.
