The table of random digits (Table B) was produced by a random mechanism that gives each digit probability 0.1 of being a 0. (a) What proportion of the first 200 digits in the table are Os? Read the table from line 101 from the top left corner line by line. This proportion is an estimate, based on 200 repetitions, of the true probability, which we know is 0.1. Give your answer to three decimal places. proportion: (b) The Probability applet can imitate random digits. Set the probability of heads in the applet to 0.1. Check "Show true probability" to show this value on the graph. A head stands for a 0 in the random digit table and a tail stands for any other digit. Simulate 200 digits (set the "Number of Tosses" to 200 and click on "Toss"). Make a note separately or on paper of the result of your 200 tosses. Assume another student used the Probability applet as described to simulate the 200 digits. Which of the statements is most likely to be true? The student got 20 zeros. The student got 100 zeros. If the student simulates, again he/she will get the same number of zeros. All of the other options are approximately equally likely.
