The U.S. Census Bureau reports that on average Americans consume 99.9 pounds of fresh fruit per year, with a standard deviation of 30 pounds. A random sample of 38 people were asked to track their fresh fruit consumption over one year. The probabilities of various scenarios regarding the sample's average consumption were calculated.

The Statistical Abstract of the United States published by the U.S. Census Bureau reports that the
average annual consumption of fresh fruit per person is 99.9 pounds. The standard deviation of
fresh fruit consumption is about 30 pounds. Suppose an analyst took a random sample of 38
people and had them keep a record of the fresh fruit they ate for one year. Appendix A Statistical

INTRODUCTION TO HYPOTHESIS TESTING Chapters 9 and 11 D orit N evo, 2013 1 INFERENTIAL STATISTICS ¢  We often use statistics to test theories. —  Theory: a prediction, or a group of predictions, about how people, physical entities, and built devices behave. ¢  Theories begin as predictions, which are then repeatedly tested in various settings to either strengthen or refute them. —  Such testing often involves statistical inference, defined as the drawing of conclusions about a population of interest based on findings from samples obtained from that population. ¢  We will cover: —  Hypothesis testing —  Analysis of Variance (ANOVA) —  Regression Analysis HYPOTHESES TESTING ¢ Statistics is very much about expectations. We aim to test specific expectations that we have about the population’s parameters using sample statistics. We call these expectations hypotheses. —  A hypothesis is some specific claim that we wish to test. ¢ We study the probability of our sample’s outcome given the hypothesized distribution of the population We believe that Our sample mean is Possible? X~N(10,2) 12 Probably yes X~N(10,2) 20 Probably not HYPOTHESES ¢ We differentiate between the research hypothesis and the null hypothesis. —  Example: A bank manager argues that, on average, people carry $50 or more in their wallet. This claim is the null hypothesis. The research hypothesis contains the other side of this claim, that is – that people carry less than $50. We can also write it as: ¢  H0: Average amount of money ≥ $50 ¢  H1: Average amount of money < $50 —  where H0 is used to notate the null hypothesis and H1 (sometimes denoted HA) is used to notate the research hypothesis, commonly referred to as the alternative hypothesis. HYPOTHESES ¢  Researchers tell you that, on average, people have 200 or fewer friends on Facebook. However, you believe that Facebook users, in fact, have more than 200 friends. You can set your hypotheses as: —  H0: Average number of friends ≤ 200 —  H1: Average number of friends > 200 ¢  A statistics professor wants to know if her section’s grade average is different than that of other sections of the course. The average for all other sections is ‘75’. To help the professor learn if her section’s grade average is different than that of other sections, we need to set up the following hypotheses: —  H0: Section’s grade average = 75 —  H1: Section’s grade average ≠ 75 THREE FORMS OF HYPOTHESES H0: Average amount of money ≥ $50 H1: Average amount of money < $50 Lower- Tail Test H0: Section average = 75 H1: Section average ≠ 75 Two- Tail Test H0: Average number of friends ≤ 200 H1: Average number of friends > 200 Upper- Tail Test -4 -3 -2 -1 0 1 2 3 4 Z The ‘equal’ sign (=, ≥, ≤) always goes in the null hypothesis A FINAL NOTE ON HYPOTHESES ¢  Hypotheses must .

The tumor suppressor gene p53 is the most frequently mutated gene in human cancers. P53 is a transcription factor that promotes apoptosis, so the protein must be maintained in an inactive state. Propose a mechanism to account for how DNA damage could trigger apoptosis through p53 (can draw it instead if choose to). You can upload either a written explanation or a drawing of the pathway. Your answer should include: a signal, a "receptor" or sensor for the signal, a transduction event, and output how p53 is converted from inactive/active states An explanation for how p53 could trigger apoptosis via transcriptional regulation.

The trophozoite stage of Entamoeba histolytica is the active, feeding stage of the parasite. It is characterized by a single nucleus and large cytoplasm that contains several vesicle and granules. The trophozoite is usually pear shaped and measures approximately 10-60 micrometres in length. After the trophozoite are released then they travel through the intestine, where they feed on bacteria and other microorganisms. They can also invade the intestinal wall and cause tissue damage, leading to symptoms such as diarrhoea, abdominal pain, and bloody stools. Some trophozoite may also enter the bloodstream and migrate to other organs such as the liver here they can cause abscesses. This is known as extraintestinal amoebiasis. After several days, the trophozoite begin to encyst in the large intestine. Encystation is the process by which the trophozoites transform into dominant cyst stage, which is resistant to environmental stresses such as desiccation and temperature change. 1. mention 10 keypoints of this entamoeba hystolytica lifecycle 2. give the book reference of this information.

The spines on these plants are modified leaves. Cacti also experiences dormancy, given the environment where they live. That is, they stopped growing in the summer and resume growing in the fall. Based on the information above: 1. What is the purpose of spines on cacti? What will happed if cacti experiences mutations that modified the spines to true leaves (broad leaves)? Why do you think so? 2. What is the purpose of staying dormant in the summer? Why do you think so? 3. What will happen if they failed to go dormant in the summer? Why do you think so? 4. Cacti stems are actually the part that primarily serve as photosynthetic site (not the leaves, they don't have leaves). Briefly describe what's unique about cacti photosynthesis. Are they C3, C4, CAM? Why do they employ that adaptation strategy?.

How much larger will the Sun get? [8] c) Which planets would be swallowed up by the Sun when it becomes a red giant?
