Dependent and independent variables: The dependent variable is the plant placed on the window sill. The independent variable is the inches that the plant grows per day. Control: the control could be the plant’s sun exposure. Collect: To collect data, one must observe the plant’s growth per day and record it accordingly for future reference. Present: to present the data, a line graph must be made to show the dependency of the growth of the plant in correlation to the plant. Analyze: analyze whether the data collected proves or disproves the hypothesis 2. The teller at the bank with brown hair and brown eyes and is taller than the other tellers.

Hypothesis: If Sally eats healthy foods and exercises regularly, then her blood pressure is 10 points lower when she does not exercise and eats unhealthy foods. Null Hypothesis: If Sally eats healthy foods and exercises regularly, then her blood pressure would remain the same as when she does not exercise and eats unhealthy foods. Experimental approach: To determine if Sally’s food intake and exercise or lack thereof affects her blood pressure, then her blood pressure must be taken both when sheShow MoreRelatedLab #12039 Words   |  9 Pagesdepartment Data security – Lab # 1 Lab Description Set-UID is an important security mechanism in Unix operating systems. When a Set-UID program is run, it assumes the owner’s privileges. For example, if the program’s owner is root, then when anyone runs this program, the program gains the root’s privileges during its execution. Set-UID allows us to do many interesting things, but unfortunately, it is also the culprit of many bad things. Therefore, the objective of this lab is two-fold: †¢ AppreciateRead MoreOrgo1 Lab 1704 Words   |  3 Pagesï » ¿Dina Karina Lab performed: 1/22/15 Chem 2203-012 Report due: 1/29/15 TA: Kavitha Akula Experiment 4A: Determination of a Partition Coefficient for Benzoic Acid in Methylene Chloride and Water, and Experiment 4B: Solvent Extraction I: Acid-Base Extraction Using the System Benzoic Acid, Methylene Chloride, and Sodium Bicarbonate Solution Objective The purpose of this experiment is to familiarize oneself with the general procedures determining a partition coefficientRead MoreLab 1 Essay806 Words   |  4 Pages1. During the install, the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective, why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a servers notion of time inRead MoreUnit 1 Lab1050 Words   |  5 Pageswith secondary hypothyroidism are low Thyroxine (T4) levels in patients with secondary hypothyroidism are high TSH levels in patients with hyperthyroidism are high Thyroxine (T4) levels in patients with hyperthyroidism are low Materials and Methods 1.
