1)Mathematicians and Statisticians abbreviate everthing - most of Math is reused English or Greek. In terms of data size or sample size: __ ___ is used to denote the population size __ ___ is used to denote the sample size.

2)Check all that apply to the Law of Large Numbers

Solution

1.   sample size = n and population size = N

2. Option (1) is correct, As n N, pˆ p, since as sample size increase the sample prorption tends to population proportion

   Option (3) is correct As n N, the sampling distribution approaches the normal distribution

   Option (4) is correct As n N, x . Since as sample size increase the sample mean tends to population mean.

   Option (5) is corect Given ˆ is the statistic which estimates the paramter , as n N, ˆ . since as sample size increases the statistic tends to acutal value of the parameter theeta.

Option (7) is coorect As n N, s . since sample size increases the sample sd is tends to population SD.
