from the data values in a sample, under repeated sampling
False, it is the standard deviation (standard error) of sample means that4. the standard deviation of a sample is smaller than the standard deviation of the parent distribution. in fact the sample standard deviation equals the population standard deviation divided by the square root of sample size (true?)
this is true of.
False5. the size of standard deviation is directly related to the size of hte data set; the larger the data set, the larger the standard deviation (false ?)
False, the distribution of the sample data gets more like that of the17. as the sample size increases, the shape of ht distribution of sample data gets more normal (true?)
distribution being sampled from. It is the distribution of sample means that this is true of.
