Course: Introduction to Statistics (Bus-172)Answer all the questions.Determine if the following statements are TRUE or FALSE. If False, write the CORRECTstatements:1. The sample mean CGPA calculated from a sample of 40 students is 0.5 largerthan the population mean CGPA, then 0.5 is a non-sampling error.2. If Z has a standard normal distribution P(Z<-3.2)=P(Z>2.3).3. For a sample size of n = 10, the standard deviation of sampling distribution ofX, i.e., oz is larger than the population standard deviation, o.
