Consider random variables X and Y with a joint pmf, given in the following table.
X Y 0 1 2 30 0 0.05 0.0625 0.021 0.125 0.25 0.02 02 0.03 0.05 0 0.1253 0.1 0.0625 0.055 0.05
a. Compute pX(x) and pY(x), namely the marginal pmf of X and Y.b. Compute the mean, variance, and squared coefficient of variation of X.c. Are X and Y independent?d. Compute the conditional expectations E[X|Y = 1] and E[X|Y > 1].e. Compute the conditional expectation E[X+2Y|X > 1, Y < 2].
To determine monthly rental prices of apartment units in San Francisco Bay area, samples were constructed in the following ways. Identify the technique used to produce each sample.
There were 3 defectives in the first batch and 5 in the second. Find a 95% confidence interval using the plus four method for the difference in the proportion of defectives.
Construct a 95% confidence interval for the proportion of votes that Jefferson will receive, and make a conclusion about Jefferson winning election.
At.05 level of significance determine if correlation between rental cost and apartment size is significant.
The average monthly gasoline purchase for a family with 2 cars is 90 gallons. This statistic has a normal distribution with a standard deviation of 10 gallons. A family is chosen at random.
The mean of a standard normal probability distribution.
The relationship between energy consumption and average car gas mileage, controlling for GDP.
Suppose there are two samples of size 6 and 7, with a rank sum of 58 in the sample of size 6. Using the Wilcox on rank-sum test, evaluate the significance of the results, assuming there are no ties.
Assume that, among residents of a large Florida subdivision, the population mean age is 65 years old, the population standard deviation is 2 years, and that the age variable is distributed normally.
Create a 98 percent confidence interval for the population mean.
Draw a tree diagram to show all possible outcomes of the experiment. Label the probability associated with each stage of the experiment on the appropriate branch.
Compute test statistic and p -value for each sample. (Negative amount must be pointed out by minus sign.)
