Brandon sold gold coins for $1,000 that he bought a year ago for $1,000. He says, "At least I didn't lose any money on my financial investment." His economist friend points out that in effect he did lose money because he could have received a 3 percent return on the $1,000 if he had bought a bank certificate of deposit instead of the coins. The economist's analysis in this case incorporates the idea of normative economics positive economics opportunity costs marginal benefits that exceed marginal costs.

To examine the potential effects on the transmission of dengue, Bian et al. (2010) infected mosquitoes from both the WB1 (laboratory created) strain and the original wild strain with dengue. Fourteen days later, the mosquitoes were allowed to feed on an artificial food solution for 90 minute. Viral titers in the food solution were then measured (in plague feeding units [pfu] per ml. The results are given below. Mosquitoes were tested in groups, and so each data value is an average for the group, measured in pfu/ml. The data have already been log-transformed using log(Y+1), to better visualize the differences.

Problem 2. Control and Data Hazards Clara, now a senior engineer, at C³ (Creative Computer Corporation) is working on a new pipelined processor. She has a benchmark that has the following characteristics: 33% ALU instructions, 27% load instructions (15% of loads are followed by instructions that use the data being loaded) 16% store instructions 24% branch instructions (58% of these branches are taken). This processor's CPI$_{int}$ is 1 (when there are no hazards). Please answer the following questions: Considering control and data hazards, please compute the overall CPI. Assume that all branch instructions cause hazards (the penalty is 1 clock cycle).
