    Of a population and one sample from it, it is known that y¯=105\overline{y} = 105, μ=100\mu = 100, s=16s = 16 and σ=15\sigma = 15. In welk interval zou 95% van de steekproefgemiddeldand liggand?


    1. FALSE: 100±1.96×16/n100\pm1.96×16/\sqrt{n}
    2. FALSE: 105±1.96×15/n105\pm1.96×15/\sqrt{n}
    3. TRUE: 100±1.96×15/n100\pm1.96×15/\sqrt{n}
    4. FALSE: 105±1.96×16/n105\pm1.96×16/\sqrt{n}
