Random number generation can be controlled with SET.SEED() functions. For example, if you need 50 numbers, use 01 ­ 50 rather than 1 ­ 50. If the seed value is identical for successive invocations of the function, then the return value is the same for each successive run of the function. Perform a simulation to determine the probability that out of the next 5 customers to rent a movie, at least 1 If you want a random digit, you can open it to any page and point.

A random number table is a series of digits (0 to 9) arranged randomly in rows and columns, as demonstrated in the small sample shown below. They use a formula with a number seed to generate the numbers, which means that the list could potentially be repeated (making the list not truly random). Continue down the column until you find 5 of the numbers whose first three digits are less than or equal to 200. Random number tables have been used in statistics for tasks such as selected random samples. • Simple random sample: Choose an SRS by giving every individual in the population a numerical label and using Table B of random digits to choose the sample. This proportion is an estimate, based on 200 repetitions, of the true probability, which we know is 0.1. 2. This proportion is an estimate, based on 15 repetitions, of the true probability, which in this case is known to be 0.1. (eg. Random number generator doesn’t actually produce random values as it requires an initial value called SEED. a.
