Exercise 1: Data Interpretation Table 1: Water Quality vs. Fish Population Dissolved Oxygen 0 2 4 6 8 10 12 14 16 18 Number of Fish Observed 0 1 3 10 12 13 15 10 12 131. What patterns do you observe based on the information in Table 1?2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.3. What would your experimental approach(s) be to test this hypothesis?4. What are the independent and dependent variables?5. What would be your control element?6. What type of graph would be appropriate for this data set and why?7. Graph the data from Table 1: Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then “Insert” the graph, or use another drawing program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg. image here.8. Interpret the data from the graph made in Question 7.Exercise 2: Testable ObservationsDetermine which of the following observations (A-J) could lead to a testable hypothesis. For the ones that are testable: Write a hypothesis and null hypothesis What would be your experimental approach? What are the dependent and independent variables? What is your control? How will you collect your data? How will you present your data (charts, graphs and types)? How will you analyze your data?1. When a plant is placed on a window sill, it grows three inches faster per day than when it is placed on a coffee table in the middle of the living room.2. The teller at the bank with brown hair and brown eyes and is taller than the other tellers.3. When Sally eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she does not exercise and eats unhealthy foods.4. The Italian restaurant across the street closes at 9 pm but the one two blocks away closes at 10 pm.5. For the past two days the clouds have come out at 3 pm and it has started raining at 3:15 pm.6. George did not sleep at all the night following the start of daylight savings. Exercise 3: Conversion For each of the following, convert each value into the designated units.1. 46,756,790 mg = _______ kg 2. 5.6 hours = ________ seconds 3. 13.5 cm = ________ inches 4. 47 °C = _______ °FExercise 4: Accuracy and Precision 1. During gym class, four students decided to see if they could beat the norm of 45 sit-ups in a minute. The first student did 64 sit-ups, the second did 69, the third did 65, and the fourth did 67. 2. The average score for the 5th grade math test is 89.5. The top 4th graders took the test and scored 89, 93, 91 and 87. 2. Yesterday the temperature was 89 °F; tomorrow it’s supposed to be 88°F and the next day it’s supposed to be 90°F, even though the average for September is only 75°F degrees! 3. Four friends decided to go out and play horseshoes. They took a picture of their results shown to the right:4. A local grocery store was holding a contest to see who could most closely guess the number of pennies that they had inside a large jar. The first six people guessed the numbers 735, 209, 390, 300, 1005 and 689. The grocery clerk said the jar actually contains 568 pennies.Exercise 5: Significant Digits and Scientific Notation Part 1: Determine the number of significant digits in each number and write out the specific significant digits.1. 405000 2. 0.0098 3. 39.999999 4. 13.00 5. 80,000,089 6. 55,430.00 7. 0.000033 8. 620.03080Part 2: Write the numbers below in scientific notation, incorporating what you know about significant digits.1. 70,000,000,000 2. 0.000000048 3. 67,890,000 4. 70,500 5. 450,900,800 6. 0.009045 7. 0.023
Hi, Welcome to JustAnswer!I can assist you with those questions. In Exercise 4 (Accuracy and Precision), it is not mentioned what is to be done? Please clarify.Thanks.
Exclude exercise 4. Please do the remaining.
Thank you so much for the work.
