ASSIGNMENT: Research a probability that is of interest. This could be anything from the probability of a major earthquake in California to the lottery. Examine the probability and evaluate the source of the information, how the probability was calculated, etc. Share your thoughts on the probability you selected and probability in general. INITIAL POST: (1) […]
If 10 of these eco-cars are randomly selected from this population, what is the probability the mean MPG will be between 30.12 mpg and 32.27 mpg?
ASSIGNMENT Given: MPG (mile per gallon Fuel efficiency) of a certain model eco-car is normally distributed with mean of 31.1 and standard deviation of 1.245. Round answers to nearest thousandth and keep in decimal format. Give full solution for each of these parts (and note the start to Part A, versus the start of Part […]
Suppose an urn contains 5 red balls, 3 white balls, and 2 yellow balls. We draw a ball from the urn at random, write down its color and return the ball to urn.
Probability (10 points) Question #1. Consider a random experiment where two fair six-sided dice are thrown. (a) (5 points) Define the sample space of this experiment. How many outcomes are possible? (b) (5 points) Show all the outcomes in the event ”the sum of both dice is 6”. What is the probability of this outcome? […]
Is the sampling method probability or nonprobability? Is the specific sampling method used in the study to obtain the sample identified and appropriate?
Population and sampling Is the sampling method probability or nonprobability? Is the specific sampling method used in the study to obtain the sample identified and appropriate? Is the sample size identified? Is a power analysis reported? Was the sample size appropriate, as indicated by the power analysis? If groups were included in the study, is […]
What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications?
Assignment What are the 4 characteristics of a binomial experiment? Can we use a binomial distribution to model this process? What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications? (Hint: Use Excels =BINOMDIST() function to find the probability) What is the […]
Calculate. Ten years ago, Amanda Cortez invested $20,000 in an account paying an annual interest rate of 5%. What is the value of the investment today?
ASSIGNMENT A company had cash and marketable securities worth $200,000 accounts payables worth $51,000, inventory of $1,501,500, accounts receivables of $5,288,128, short-term notes payable worth $220,000, other current liabilities of 100,000, and other current assets of $121,800. Calculate the company net working capital and describe how managers manage the firm working capital. (2 Marks) Your […]
What sampling procedure was used? Discuss in detail and in your own words how the sample was selected and collected.
Sampling Techniques In addition to determining how the data will be collected and which measures to use, when conducting research, researchers must decide who will be asked to participate. Obtaining an adequate sample is one of the most important factors in conducting research. Locate two research studies on Proquest or EbscoHost one that utilized a […]
Write a sentence for each of the probabilities explaining what those probabilities mean in context of days of precipitation in your chosen city.
Topic: Poisson Probability Distribution The Poisson Distribution is a discrete probability distribution where the number of occurrences in one interval (time or area) is independent of the number of occurrences in other intervals. April Showers bring May Flowers!! Research the “Average Amount of Days of Precipitation in April” for a city of your choice. In […]
