Discrete probability distribution

The most appropriate measure of center of this data set would be the median, or the arithmetic average. The median would be more suitable because the mean is more heavily influenced by outliers. In a skewed distribution, the mean would be pulled more towards the tail of the data where outliers exist, and the average value would be greater than that of the median. In this case, using the 1.5 x IQR rule, any departure time less than 19.5 or greater than 16.5 is an outlier. Hence, with multiple outliers

values between $175,000 and $250,000 have the same probability of being the actual appraised value. What is the appropriate distribution for simulating appraisal values? A) continuous uniform B) triangular C) binomial D) discrete uniform E) normal Answer: A Page Ref: 415 Topic: Role of Computers in Simulation Difficulty:

State whether the variable is discrete or continuous. The # of keys on each student's key chain. 2. Decide whether the experiment is a binomial experiment. Explain why by citing the properties of binomial experiments. Testing a pain reliever using 20 people to determine if it is effective. The random variable represents the number of people who find the pain reliever to be effective. 3. Use the binomial probability distribution to answer the following probability questions. According to government

“Discrete data are values based on observations that can be counted and are typically represented by whole numbers” (Donnelly, 2013, p. 24). In this scenario, the number of guests per party represents discrete data. One of the owners of Mi Casa Front Porch Restaurant is interested in the number of guests per party that attend the restaurant. In order to achieve maximum capacity efficiently, he is trying to determine table size and placement based on the number of guests per party. To help out the

Gender is an example of the a. ordinal scale. b. nominal scale. c. ratio scale. d. interval scale. ANS: b 2. The scale of measurement that is used to rank order the observation for a variable is called the a. ratio scale. b. ordinal scale. c. nominal scale. d. interval scale. ANS: b 3. Some hotels ask their guests to

the one of the following two ways: better modeling of the discrete musical structure of the piece being transcribed [2,3] or by better adapting to the timbral properties of the source instrument [4,5]. Combining the above two approaches are difficult. Hidden Markov or semi-Markov models are widely used as the standard approach to model discrete musical structures. This approach needs fast dynamic programming for inference. To combine discrete models with timbral adaption and source separation, it

measured as a percentage, return on investment. What type of variable is return on investment? A. Qualitative B. Continuous C. Attribute D. Discrete 4) What type of variable is the number of robberies reported in your city? A.

Maintenance plays a relevant role in business success related to offshore oil and gas. It is a key for ensuring the efficient use of equipment as well as an efficient production process and, hence on the profitability since failures impacts the performance of subsea equipment both in terms of production accessibility and repetitive breakdowns or running in bad condition may contribute to lower product quality, increased energy consumption and reduced revenue. Thus, the objective of maintenance is

A. 0 B. 1 C. 2 D. 3 13) A dot plot shows A. the general shape of a distribution B. the mean, median, and mode C. the relationship between two variables D. the interquartile range 14) The test scores for a class of 147 students are computed. What is the location of the test score associated with the third quartile?

that might be best for summarizing the data, if you were to collect a sample. "Descriptive statistics is the summary of important aspects of a data set" (Jaggia & Kelly, 2014). To use descriptive statistics, I would use frequency distribution. "Frequency distribution of qualitative data groups the data into categories then records the number of observations that fall into each category" (Jaggia & Kelly, 2014). If I use ordinal data, it will allow us to categorize and rank the data. The data will
