Question: To continue problem, a second random sample of 12 adult crabs was collected, and it revealed that 4 individual crabs had been infected. Revise your probability distribution, and plot it. Give a credible set of highest posterior probability close to 95%.
Problem: An article in Forbes discusses the problem of oil and gas reserves around the world.6 Forecasting the amount of oil available is difficult. If the average number of barrels that can be pumped daily from an oil field is a normal random variable with mean 7,200 barrels and standard deviation 505 barrels, and a random sample of 20 days reveals a sample average of 6,100 barrels and standard deviation of 800, give a 95% highest-posterior-density credible set for the average number of barrels that can be pumped daily.
Diastolic blood pressure (DBP) values were measured for 150 patients using two medical devices. The mean DBP values using the two devices are 120 and 122 respectively. Also the standard deviation of the di fference of the measurements is 0.634. Te..

a. what is the point estimate of the population mean? b. what is the point estimate of the population standard deviation?
Construct the two fold association table and calculate the coefficient of association - number of passed candidates exceeded the number of failed candidates by 310. Boys failing in the examination numbered 88.
The lengths of pins produced by a machine follow a normal distribution with mean 2.54 cm and standard derivation 0.04 cm.
Electrical connectors manufactured by a supply company last an average of 18.2 months and follow a normal distribution with a standard deviation of 1.7 months.
Dr. Mack Lemore, an expert in consumer behavior, wants to estimate the average amount of money that people spend in thrift shops. He takes a small sample of 8 individuals and asks them to report how much money they had in their pockets the last ti..
Find the probability that X is between 70 and 110. (Round your answer to the nearest whole number percent and include the percent symbol.)
find the standard deviation of the distribution in the following situations. a mensa is an organization whose members
A position control system for a DC motor is shown in Figure AP7.8. Obtain the root locus for the velocity feedback constant K, and select K so that all the roots of the characteristic equation are real (two are equal and real). Estimate the step r..
An airline has flights from a small airport connecting with Ohare. These small planes carry 30 passengers. The airline knowing that only 85% of booked passengers routinely show up for a randomly selected flight routinely sell 31 tickets for each f..
