Course: Introduction to Statistics (Bus-172)<br>Answer all the questions.<br>Determine if the following statements are TRUE or FALSE. If False, write the CORRECT<br>statements:<br>1.. When sample size (n) increases standard deviation of sampling distribution of<br>i, i.e., o, increases.<br>2. Z has a standard normal distribution then P(Z<-0.8) =P(Z<0.8).<br>3. X has a normal distribution with mean 1. Then P(X < 1) = 0.5.<br>4. The sampling distribution of sample mean will be normal when a sample of<br>size 25 is drawn from a skewed population distribution.<br>5. The sample mean CGPA calculated from a sample of 40 students is 0.5 larger<br>than the population mean CGPA, then 0.5 is a non-sampling error.<br>6. If Z has a standard normal distribution P(Z<-3.2)=P(Z>2.3).<br>
