1. You want to see if there is evidence to reject the hypothesis that 70% of Hope students have never left the United States. You obtained a random sample of 135 Hope students and found that 97 of them have never left the US. (a) Calculate the observed proportion of Hope students in your sample who have never left the US. What is this number called? What symbol do we use for this number? (b) What is the population of interest here? (c) Dene the parameter of interest here. What symbol do we use for this parameter? (d) Write down in symbols the hypothesis that is made in the question about the proportion of Hope students who have never left the US. (e) Do you think the observed sample proportion is likely if the percentage of Hope students who have never left the US is really 70%? (f) Give an observed proportion that you are unlikely to observe if the percentage of Hope students who have never left the US is really 70%. (g) In the simulation app, i. What value of \pi should you set? ii. What value of n should you set? iii. In 1000 simulations, how often did you get simulated values which were as or more extreme than what you saw? State a fraction of times. iv. Report the SD of the simulated proportions. (h) Based on your simulation, would you reject the hypothesis that 70% of Hope students have never left the United States?

Which statement is false about the Na*K* ATPase? K*-dependent dephosphorylation favors return of the transporter to the original conformation. ATP interacts covalently by phosphoryl group transfer to the substrate. The free-energy change of ATP hydrolysis drives cyclic changes in the protein conformation of the transporter. The pumping of Na* and K* across plasma membranes accounts for nearly two-thirds of the energy consumed by the human brain and kidney.

II. Given the Block Diagram: X F Y Z And Requirements: 3 Inputs labeled as X, Y, Z with X the MSB Active Low Output labeled as Fsss Operation: The output will be active when both X and Y are '0' or Y and Z are both '1.' The output will be '1' for all other cases. A. Create the truth table and develop the canonical SOP equation using the above specifications. Then implement your equation using schematic capture and simulate. B. Simplify your equation from (A) using Boolean algebra (showing the theorems you used) and check your algebra using a Karnaugh Map. Simulate your new equation using schematic capture. C. Using your simplified equation from (B), create a VHDL file and simulate, but change the output variable to Gttt, where ttt are the last three digits of another partner's SID. To get full credit for your vhdl file, be sure to include Comments as included on previous page.
