Current Attempt in Progress Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed. A 95 % confidence interval for a difference in means $\mu_1 - \mu_2$ if the samples have $n_1 = 120$ with $\bar{x}_1 = 253$ and $s_1 = 46$ and $n_2 = 160$ with $\bar{x}_2 = 237$ and $s_2 = 50$, and the standard error is $SE = 5.77$. Round your answers to three decimal places. The 95 % confidence interval is $4.691$ to $27.309$

A researcher treats a DNA sample and a plasmid with the $amp^R$ and $lacZ$ (for the enzyme $\beta$-galactosidase) genes with the restriction enzyme EcoRI with the goal of making recombinant DNA molecules. The researcher places the $lacZ$ gene in the cloning region so that it is disrupted by DNA inserts. Place the remaining steps for this process in the correct order. Not all steps will be used. Treat DNA with the restriction enzyme. Answer Bank Blue colonies that survive on the culture medium contain the recombinant plasmid. Grow cells containing the recombinant plasmid in a medium with ampicillin and X-gal (a galactose derivative). All the fragments have the sticky ends 5'-GAATTC-3'. Remove colonies containing the recombinant plasmid from the culture medium and continue growing. All the fragments have identical sticky ends: 5'-AATT-3'. White colonies that survive on the culture medium contain the recombinant plasmid. Use DNA ligase to join the sticky ends of the DNA sample and the plasmid.

Virtual functions allow you to: - create an array of type pointer-to-base class that can hold pointers to derived classes. - create functions that can never be accessed. - group objects of different classes so they can all be accessed by the same function code. - use the same function call to execute member functions of objects from different classes.

3-138. The number of cracks in a section of interstate highway that are significant enough to require repair is assumed to follow a Poisson distribution with a mean of two cracks per mile. (a) What is the probability that there are no cracks that require repair in 5 miles of highway? (b) What is the probability that at least one crack requires repair in 1/2 mile of highway? (c) If the number of cracks is related to the vehicle load on the highway and some sections of the highway have a heavy load of vehicles whereas other sections carry a light load, how do you feel about the assumption of a Poisson distribution for the number of cracks that require repair?
