    I still get confused on knowing when we have to use "mu" and when we don't.

    "mu" is used when trying to solve the mean of a population. the "x bar" is used when we take a sample of the whole population.

    HI my name is Carolina Munoz. Stratified sampling is when you divide the population into two different subgroups then you draw a sample from each subgroup.

    to find UF and LF you first subtract Q3-Q1=n and what ever the difference of the two number are you multiply them at the end of the LF and UF

    Ex: LF: Q1-1.5*n=
    UF: Q3-1.5*n=

    This is from my notes from Friday!!
