The process analysis is used when we tell someone how to do something or explain how something works. We might explain to someone how to plant a garden or how a computer program works. Our explanation is effective if we are able to break up the process into steps and clearly explain each one. Often when we give instructions orally, we also are able to demonstrate the procedure; however, in writing, we rely only on words, so not only must each step be clear, but we also must include descriptive detail so the reader can visualize the steps. The topic sentence of the process paragraph should state the topic (the process to be explained) and an attitude or viewpoint about the process. Sometimes, we state the purpose of learning the process in the topic sentence. Look at the following examples of topic sentences for process paragraphs. To make the perfect peanut butter sandwich, follow these steps. Since most doctors have little time to spend with their patients, everyone should know how to prepare for a doctor's appointment.

The leading and the lagging strands differ in that the leading strand is synthesized at twice the rate of the lagging strand. the lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are ultimately stitched together. the leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end. the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction.

A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief executive office (CEO) was at least 9 years. A survey of 69 companies reported in The Wall Street Journal found a sample mean tenure of 7.4 years for CEOs with a standard deviation of s=5.2 years (The Wall Street Journal, January 2, 2007). You don't know the population standard deviation but can assume it is normally distributed. You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of α=0.002. In other words, your claim is that the mean tenure for a CEO was less than 9 years. Your hypotheses are: H0: μ ≥ 9 H1: μ<9 What is the test statistic for this sample? test statistic = -2.5559 What is the p-value for this sample? p-value = 0.0053
