(a) 3 points possible (graded) The National Assessment of Educational Progress tested a simple random sample of 1000 thirteen year old students in both 2004 and 2008 and recorded each student's score. The average and standard deviation in 2004 were 257 and 39, respectively. In 2008, the average and standard deviation were 260 and 38, respectively. Your goal as a statistician is to assess whether or not there were statistically significant changes in the average test scores of students from 2004 to 2008. To do so, you make the following modeling assumptions regarding the test scores: represent the scores in 2004. are iid Gaussians with standard deviation . , which is an unknown parameter. represent the scores in 2008. are iid Gaussians with standard deviation . , which is an unknown parameter. are independent of . You define your hypothesis test in terms of the null (signifying that there were not significant changes in test scores) and . You design the test where represents the quantile of a standard Gaussian. Hint: Under , the test statistic is distributed as a standard Gaussian: You are encouraged to check this.(Compute the mean and variance and recall that the sum of iid Gaussians is again Gaussian.) What is the largest possible value of so that has level ? unanswered If is designed to have level , would you reject or fail to reject the null hypothesis given these data? Reject Fail to reject unanswered What is the p-value for this data set? unanswered

The

pK_(a)

value for N 1 of adenine is 3.64 , whereas the

pK_(a)

value for N 1 of guanine is 9.50 . Explain this difference. The energy of N1 in a purine ring is lowest when it is in its

trivalent form. Thus, protonated and therefore tetravalent and

charged N1 in adenine readily gives up its proton to water (has a fow pKa value) to yeld its

trivalent form. In contrast, the trivalent N1 of neutral guanine resists donating its proton to water (has a high pKa value) to yield a divalent and therefore

charged ion.

12400 Hint Submit Answer Question 9 of 24 Signal peptidase removes the signal nentide from the orrorino molymontid. Protein is transported out of the ER. Answer Bank Ribosome docks to a translocon. SRP moves the ribosome to the ER membrane. The remainder of the polypeptide is moved into the ER lumen. Translation resumes. SRP binds to the signal peptide and translation stops. The growing polypeptide crosses the ER membrane through translocon.
