  • Statisics Question Help Please -

    Confidence interval using proportions:

    CI95 = p + or - (1.96)(√pq/n)
    ...where + or - 1.96 represents 95% confidence using a z-table.

    Note: p = 55/450 (convert to a decimal); q = 1 - p; and n = 450 (sample size).

    I'll let you take it from here.
