1. The standard deviation of all possible sample proportions increases as the sample size increases. (Points : 1)TrueFalse2. For non-normal populations as the sample size (n) _________ the distribution of sample means approaches a/an __________ distribution. (Points : 1)decreases uniformincreases normaldecreases normalincreases uniformincreases exponential3. The central limit theorem states that as sample size increases the population distribution more closely approximates a normal distribution. (Points : 1)TrueFalse4. If the sampled population has mean 48 and standard deviation 16 then the mean and the standard deviation for the sampling distribution of for n = 16 are (Points : 1)4 and 1.12 and 4.48 and 4.48 and 1.48 and 16.
