Lab report on identification of two unknown metal, based on their specific heat capacities. The introduction must include the purpose of the experiment, background information thermal energy, and the law of conservation of energy. Hypothesis. Step by step method. Materials. Variables (independent-dependant-and control) and how to manipulate them. Safety precaution. Analysis and conclusion.

Set up the ray box so the light is it directed at the prism at an
angle of 50 degrees
Find the value of the prism index of refraction using Snell's
law
Find the angle between the ray entering the prism and the ray
leaving the prism
Draw a labelled diagram showing your experiment and explain the
principle of refraction

Scenario: you isolate a new drug that seems to be particularly effective at inhibiting a metabolic pathway in tumor cells. You want to do an experiment that compares global changes in the number and types of different proteins in cells that are treated with the compound vs. untreated cells. how can this be accomplished experimentally.

ou are interested in testing the effectiveness of a new program designed to teach reading skills to elementary school students, describe how you would use a experimental design design to test the effectiveness of the program. Which type experimental design would you deploy? What type of conclusion can be drawn from the experiment?

You conduct a QTL mapping experiment to find the genes that contribute to variation in flower color in a plant species. You find that for genetic marker A, the mean flower color is significantly darker in individuals with the A1 allele than for individuals with the A2 allele. What do you conclude? Only one sentence needed for this answer.

By now, you should have noticed that the formulas for statistics follow a pattern: Observed Value From Your Experiment minus the Expected Value From a Distribution, all divided by the Standard Error of the sample distribution. Explain in your own words how this fit into the Chi-square test for independence between two variables.

(A) Suppose two coin are tossed, determine the sample space and find two sigma field over the sample. (B) From the experiment also give example of a set that is not a sigma field (C) With examples, define and explain in details the concept of (a) Probability space (b) Probability Measure (c) sigma algebra or sigma field

An experiment consists of rolling 1 red die, 1 white die, and 1 blue die and noting the result of each roll. The dice are fair, and all out comes are equally likely,
What is the probability that the SUM of the results on the three dice is 7?
What is the probability that the sum is an odd number?
Please explain in detail.

What are the implications of assuming that animals can learn R-O associations in an instrumental conditioning procedure? Describe a real experiment providing evidence of R-O associations in nonhuman animals. Indicate how S, R, and O might organize hierarchically. Give a laboratory example and a daily-life example of such hierarchical organization.
