For any population with mean Î¼and standard deviation.  The mean, or center of the sampling distribution of, is equal to the population mean Î¼:Î¼ x = Î¼.  The standard deviation of the sampling distribution is Ï/â n, where n is the sample size: Ï x = Ï / â n.
Usually a child should be 13 or older to ride in the front seat. If the child is too small then the front airbags can be dangerous and they may still need a booster seat. When â¦ they outgrow booster seats then they should be large enough to ride on the seat with just seatbelts. Always make sure they are buckled up!
