    A person asks, "what do you think is the ideal number of children for a family to have?" The 497 females who responded had a median of 2, mean of 3.02, and a standard deviation of 1.81. How do I find the point estimate of the mean and the standard error of the sample mean?

    Point estimate of a mean
    A Gss asked, "what do you think is the ideal number of children for a family to have?" The 497 females who responded had a median of 2, mean of 3.02, and a standard deviation of 1.81. How do I find the point estimate of the mean and the standard error of the sample mean?

    I don't understand the definition nor can I find a formula to do so. Help me please.
    Answer
    Given Sample mean = 3.02
    Sample standard deviation S =1.81
    The point estimate of population mean is the sample mean (Sample means tends to population mean by central limit theorem).
    The point estimate of population mean =Sample mean = 3.02
    Standard error of the sample mean = =0.081189
    where S is the sample standard deviation .
