      The probability of answering exactly 4 wrong is a binomial probability of B(24, 0.8, 4), which is , which is almost zero. If you use TI calculator use binompdf (24, 0.8, 4). Check your calculator using the following code: 2nd DISTR 0 binompdf (24, .8, 4) The probability that you will answer exactly 4 correct is B(24, 0.2, 4) = 0.196

      The power is a probability and it is defined to be the probability of rejecting the null hypothesis when the alternative hypothesis is true. After plugging in the required information, a researcher can get a function that describes the relationship between statistical power and sample size and the researcher can decide which power level they ...
