Question

212 6. Sample statistics for variables in a data set should only be calculated for astudy a cross-sectional Any normal distribution may be used to find critical values to construct a confidence interval for a proportion 2 For a variable with a bimodal distribution, it is possible for the mean to be the same as the median. 8. d) Values more than 2 standard deviations from the mean should always be removed before analyzing the data e) 19. A five-number summary may be used to determine the shape of the distribution for a variable M. A normal distribution may be bimodal

Explanation / Answer

F) a normal distribution is a unimodal distribution which has only one peak and bell shaped curve . where as bimodal can have two peaks.

So normal distribution is can't be a bimodal

It is false.

E) yes it's true we can find the shape and distribution of a variable.

D) yes it's true . We have to remove from analysis because those are known as unusual.

C) it is false . If it is a symmetrical distribution then all measures mean median mode are same.
