19. Pick the correct answer.
| When a gene of interest has been inserted into a plasmid vector, the result is called _____ DNA. | |||||||||||
|
| Restriction sites are often DNA _____, which means that both DNA strands constituting the restriction site have the same DNA sequence but in _____ orientation. | |||||||||||

The restriction enzyme XYZ-1 cuts DNA in one strand of a double-stranded DNA molecule at the palindromic sequence 5′-GAATTC-3′. What is the sequence of the opposite strand also cleaved by this restriction enzyme? |

8. Research Question: A nutritionist claims that the mean daily consumption of fiber for 20-39-year-old males is less than 20 grams per day. (The National Cancer Institute recommends that individuals consume 20-30 grams of fiber per day) In a survey of 457 males who were 20-39 years old, conducted by the U.S. Department of Agriculture, it was found that the mean daily intake of fiber was 19.1 grams, with standard deviation of 9.1 grams. Decide whether there is enough evidence to support the nutritionist’s claim at α=.05. If you lower the level of significance to α=.01 does your decision change. Explain.

1) Assume that a sample is used to estimate a population mean μμ. Find the 98% confidence interval for a sample of size 514 with a mean of 70.8 and a standard deviation of 14.5. Enter your answer accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
__ < μ < __
2) Assume that a sample is used to estimate a population mean μμ. Find the 99.5% confidence interval for a sample of size 457 with a mean of 60.2 and a standard deviation of 15.6. Enter your answer accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
