Data Course code: CHEM 141 SCENARIO 5: Study Habits and Test Performance A group of students in a class notice that their test scores vary, even though they study similar amounts. They want to determine if different study habits affect test performance. The students note down the study hours of each student and their corresponding test scores. They also survey students about their study methods, such as reading notes, practicing problems, or group study. The students speculate that students who engage in active study methods, such as practicing problems, will perform better on tests compared to those who passively review notes. They begin by…

Data Course code: CHEM 141 SCENARIO 4: Ripeness of Bananas A grocery store employee, James, notices that customers sometimes complain about bananas being either too ripe or not ripe enough. The store wants to determine if there is an optimal ripeness stage for bananas, James measures the firmness and sweetness of bananas at different ripeness at different ripeness stages. He also records customer feedback on banana preference. James feels that bananas with a moderate level of firmness and sweetness will be the most preferred by customers. He offers customers samples of bananas at different ripeness stages-under rip, moderately ripe, and…

Question 19

How is scientific writing different from the style of writing that you learned in ENG 111?  (Select all that are correct.)   Group of answer choices a. Scientific writing is concise, written in 3rd person, and uses past tense. b. Science writing uses lots of colorful language to describe visual reactions to the experiment. c. Science writing uses lots of personal pronouns (e.g., I, me, we, you, your, our) to show ownership of the results and personal attention to directions. d.Science writing assumes the reader already knows how to do the experiment that is the subject of your paper. e.Science writing may include references that are from peer reviewed sources.

10. A scientist performs an experiment and then records the times required for a certain chemical reaction to occur. The times for the reactions to occur are normally distributed and have a mean time of 38 s and a standard deviation of 2.3 s. Use z-score tables or technology to answer the following questions. a) What percentage of chemical reactions occur between 41 s and 43 s? b) What percentage of chemical reactions occur in less than 39 s? Page 5 STATISTICS-REVIEW ASSIGNMENT c) If 200 experiments are performed in the same manner as above, how many can the scientist expect to have chemical reactions that take longer than 43 s?

McGraw Hil ALEKS CHEMISTRY-Gener... esc E ! 1 MEASUREMENT AND MATTER Adding or subtracting and multiplying or dividing measurements Explanation -1 gml1 Q A 1 A chemistry student must write down in her lab notebook the concentration of a solution of sodium thiosulfate. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.500 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 96.6 g. She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 97.7 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant…
