Use a random-number table to get a list of 10 random numbers between 1 and 99 beginning at row 2, block 2. 65321 85623 10204 50218 20321 22315 98532 91972 39800 45670 20510 10451 92012 59826 35456 79289 91483 29754 45652 98653 45863 36963 15326 78952 45678 10100 91251 37041 13712 14672

Use flat random numbers to estimate .

The data gathered from a survey of a random group of people about their smoking habits and their bodily weights are: a11 =159, a12 =203, a13 =10, a21 =285, a22 =500, a23 =38, a31 214, a32 -300, a33 =28, a41 =113, a42 =189, a43 =30, a51 =467, a52 1,969, a53 71 The following contingency table was created based on the above data, where you will need to calculate the grand total, the total for each row, and the total for each column on your own before answering the question that appears after the table. Very heavy Heavy Moderate Light SMOKING STATUS Non-Smoker Total BODILY Normal 159 285 214 113 467 WEIGHT Overweight 203 500 300 189 1,969 - STATUS Underweight Total 10 38 28 30 71 Calculate the probability of someone who has normal weight, given that the individual is non- smoker (For answers up to four decimal places, enter the number in the box below without rounding it. For answers that have more than four decimal values, round your answer to four decimal places).
