Karan negi 12.2 12.3 We use equation 2 to find out probability: F(t)=1 – e^-Lt 1-e^-(0.4167)(10) = 0.98 almost certainty. This shows that probability of another arrival in the next 10 minutes. Now we figure out how many customers actually arrive within those 10 minutes. If the mean is 0.4167‚ then 0.4167*10=4.2‚ and we can round that to 4. X-axis represents minutes (0-10) Y-axis represents number of people. We can conclude from this chart that the highest point with the most visitors

Sampling and Measures of Central Tendency and Dispersion Introduction: Overall Job Satisfaction (OJS) was the variable selected for this exercise because it lends itself to measures of central tendency and dispersion. The data are quantitative and continuous in nature. Data Selected: The instructions for the exercise suggested a sample of approximately 30 individuals from one of eight variables. There were 288 measures of OJS. Every ninth individual was selected resulting in thirty-two

Hadley Smith uses indirect and direct characterization to evince how Hadley is a clumsy and unlucky person. Hadley first reveals her clumsy sides by forgetting her stuff‚ making everything drop on the floor or being late for her plane. Not only she misses her plane‚ but she also has to sleep in a tiny airport chamber‚ being claustrophobic. Smith says “Or later: if she hadn’t given herself a paper cut while printing out her ticket‚ if she hadn’t lost her charger‚ if there hadn’t been traffic on the

consecutive points falling on one side of the centerline When the process is in statistical control‚ find the false alarm probability (Type-I error) for each case. The corresponding probability measures are obtained from the Normal table as P(3 " Z) = 0.00135 P(2 " Z) = 0.02275 P(1 " Z) = 0.1587 Solution: ! i) Use the Binomial distribution to ! calculate the probability measures. ! 3! 3! P(Y ! 2 n = 3‚ p = 0.02275) = (0.02275)2 (1" 0.02275) + (0.02275)3 = 0.00153 2!1! 3!0! Type-1

Procedures This study will use a selecting informant sampling procedure‚ which will allow to interview a specific member of each school with will allow to obtain a specific and bias information about each athletic program and the results of the presence of medical provider during practices and games of any athletic activity. By analyzing each high school in the state of Oklahoma between classes 3A and 6A football programs‚ the primary researcher will be attempting to measure the results of the procedures
