Find the probability for a roll of two dice. Rolling a sum less than 5 (the sum is found by adding the 2 faces of the dice). (Round your answer to 3 decimal places)

Do the successive digits in the decimal expansion of n behave as though they were selected from a random number table (or came from a computer's random number generator)? (a) Let po denote the long run proportion of digits in the expansion that equal 0, and define p,, ..., Pg analogously. What hypotheses about these proportions should be tested? O Ho: P1 = P2 = . .. = Pg = 0.10 H: all P; + 0.10 O Ho: P, = P2 = = P. = 0.10 H: at least one p; + 0.10 O Ho: Po = P, = ... = P, = 0.10 H: all p; + 0.10 O Ho: Po = P, = ... = P, = 0.10 H: at least one p; + 0.10 What is df for the chi-squared test? df = (b) H, of part (a) would not be rejected for the nonrandom sequence 012... 901 ... 901.... Consider nonoverlapping groups of two digits, and let p;; denote the long run proportion of groups for which the first digit is i and the second digit is j. What hypotheses about these proportions should be tested? O Ho: Pij = 0.01 for i and j = 1,2,...,9 H: at least one Pi * 0.01 Hoi Pij = 0.10 for i and j…

You are playing Farkle.What is the probability to roll exactly 100 points in one roll?  Round the answer (as decimal fraction, not in percent) to three digits after the decimal point.

Find the probability of throwing a sum of 8 at least 2 times 8 throws of a pair of fair 6-sided dice. Answer to the nearest 0.0001.

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 8th percentile of the data is 16 hours.   Based on the given information, determine if the following statement is true or false. The first quartile is less than 16 hours.

Please answer all parts and round your answers to 4th decimal points. Thank you!
