    Type I/II Error

    P1:
    avg 147.6
    std dev 4.971027169
    n = 19

    P2:
    avg 149.4
    std dev 5.460973
    n = 10
    Given this data for two samples..and using α = 5%, then Using a β = 10%, what sample size should be obtained from each process to assure meeting the Type I and Type II error constraints if the acceptable difference tolerance is δ = 1.9 ?

    I'm not really sure where to start so any suggestions would be greatly appreciated.
