Homework Help: Tdistribution to construct a confidence interval question

  1. Mar 10, 2012 #1
    The following are summary statistics for a data set. Would it be appropriate to use the
    Student's t- distribution to construct a confidence interval for these data?
    Explain clearly!

    Sample size = 10
    Mean = 8.905
    Median = 6.105
    Standard deviation = 9.690
    Minimum = 0.512
    Maximum = 39.920
    Q1 = 1.967
    Q3 = 8.103

    My answer would be it would be appropriate since n is less than 40(small sample size), we can use t distribution

    also the population should be normally distributed

    Any other explanations guys
