Suppose you just received a shipment of eight televisions. Two of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one does not work?
Use the relative frequency approach to construct a probability distribution for the number of tests taken.
Using the paired t test because the samples are correlated with each other could be another avenue. This would help us find the p-value and look at the statistical significance in evaluating the quality of care or outcomes in a medical home.
Standard deviation of 7. At 0.01 significance level, is there more variation in first population?
Calculate the sample statistic and standard error you will use to create the test statistic.
At one excavation site 8641 pot shards have been found that not yet been cleaned and identified. What is the probability that:
Comment on your statistical findings? Do you agree with your initial statement regarding the preference of an ANOVA over a t-test when examining more than two groups?
X is a normally distributed random variable with mean 10 and variance 24. a. Find P(X bigger 14) b. find P(8 smaller X smaller 20)
Let X1, ..., Xn be a random sample from a two-parameter exponential distribution, Xi ~ EXP (theta, eta). (a) Assuming it is known that eta = 150, find a pivotal quantity for the parameter theta based on the sufficient statistic.
Develop a 99% confidence interval for the population proportion.
A researcher believes that if she uses a different text the students will score differently on the standardized test but she doesn't know what the difference is. The test had a mean of 110 and a σ of 12.
In the Willow Brook National Bank waiting line system (see Problem 1), assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 36 customers per hour or 0.6 customer per minute.
A test indicates the presence of a particular disease 90% of the time when the disease is present and the presence of the disease 2% of the time when the disease is not present.
