1. If a population is uniformly distributed, the means of the samples of size 30 drawn randomly from this population are also uniformly distributed. (Points : 8) True

False

2. The standard deviation of the sample means is called the standard error of the mean. (Points : 8) True

False

3. If the observations on the units in a sample cannot measured but can only be classified and counted, sample proportion rather than sample mean is more meaningful. (Points : 8) True

False

4. The sample proportion is computed by dividing the frequency with which a given characteristic occurs in a sample divided by the number of items in the sample. (Points : 8) True

False

5. The distribution of sample proportions can be approximated by a binomial distribution. (Points : 8) True

False
