uniform probability distribution examples and solutions

Let. It can be completed by auditors and other. What is the probability that the duration of games for a team for the 2011 season is between 480 and 500 hours? State the values of a and b. CFI is the official provider of the global Financial Modeling & Valuation Analyst (FMVA)™FMVA® CertificationJoin 350,600+ students who work for companies like Amazon, J.P. Morgan, and Ferrari certification program, designed to help anyone become a world-class financial analyst. In statistics and probability theory, a discrete uniform distribution is a statistical distribution where the probability of outcomes is equally likely and with finite values. Suppose the time it takes a student to finish a quiz is uniformly distributed between six and 15 minutes, inclusive. Monte Carlo simulation is a statistical method applied in modeling the probability of different outcomes in a problem that cannot be simply solved, due to the interference of a random variable. The data follow a uniform distribution where all values between and including zero and 14 are equally likely. Find the probability that a random eight-week-old baby smiles more than 12 seconds. On the average, a person must wait 7.5 minutes. However, there is an infinite number of points that can exist. The percentage of the probability is 1 divided by the total number of outcomes (number of passersby). Therefore, each time the 6-sided die is thrown, each side has a chance of 1/6. Let X = the time, in minutes, it takes a student to finish a quiz. The probability P(c < X < d) may be found by computing the area under f(x), between c and d. Since the corresponding area is a rectangle, the area may be found simply by multiplying the width and the height. Solve the problem two different ways (see Example 3). Uniform distribution can be grouped into two categories based on the types of possible outcomes. A good example of a discrete uniform distribution would be the possible outcomes of rolling a 6-sided die. The number of values is finite. McDougall, John A. Suppose the time it takes a nine-year old to eat a donut is between 0.5 and 4 minutes, inclusive. A good example of a continuous uniform distribution is an idealized random number generator. a = smallest X; b = largest X, The mean is [latex]\displaystyle\mu=\frac{{{a}+{b}}}{{2}}\\[/latex], The standard deviation is [latex]\displaystyle\sigma=\sqrt{{\frac{{({b}-{a})}^{{2}}}{{12}}}}\\[/latex], Probability density function: [latex]\displaystyle{f{{({x})}}}=\frac{{1}}{{{b}-{a}}} \text{ for } {a}\leq{X}\leq{b}\\[/latex], Area to the Left of x: [latex]\displaystyle{P}{({X}{<}{x})}={({x}-{a})}{(\frac{{1}}{{{b}-{a}}})}\\[/latex], Area to the Right of x: [latex]\displaystyle{P}{({X}{>}{x})}={({b}-{x})}{(\frac{{1}}{{{b}-{a}}})}\\[/latex], Area Between c and d: [latex]\displaystyle{P}{({c}{<}{x}{<}{d})}={(\text{base})}{(\text{height})}={({d}-{c})}{(\frac{{1}}{{{b}-{a}}})}\\[/latex], [latex]\displaystyle{P}{({x}{<}{k})}={(\text{base})}{(\text{height})}={({12.5}-{0})}{(\frac{{1}}{{15}})}={0.8333}\\[/latex], [latex]\displaystyle{P}{({x}{>}{2}|{x}{>}{1.5})}={(\text{base})}{(\text{new height})}={({4}-{2})}{(\frac{{2}}{{5}})}=\frac{{4}}{{5}}\\[/latex], http://cnx.org/contents/30189442-6998-4686-ac05-ed152b91b9de@17.41:36/Introductory_Statistics, http://cnx.org/contents/30189442-6998-4686-ac05-ed152b91b9de@17.44. Ninety percent of the smiling times fall below the 90th percentile, For the first way, use the fact that this is a, For the second way, use the conditional formula (shown below) with the original distribution. It is used to. The histogram that could be constructed from the sample is an empirical distribution that closely matches the theoretical uniform distribution. Find the 90th percentile. Refer to Example 1 What is the probability that a randomly chosen eight-week-old baby smiles between two and 18 seconds? The data in the table below are 55 smiling times, in seconds, of an eight-week-old baby. Write the distribution in proper notation, and calculate the theoretical mean and standard deviation.
