An experiment about the gender success in Math courses is performed and the following results are obtained. 150 out of 270 male participants could get a grade above 50. On the other hand 135 out of 228 female participants obtained a score above 50. Design and perform a test to see if the difference is statistically significant.

5. Suppose a random variable, x, arises from a binomial experiment. If n = 23, and p= 0.22, find the following probabilities using technology. show work

1. P (x = 21)
2. P (x = 6)
3. P (x = 12)
4. P (x<=14)
5. P (x >=17)

6. P (x <= 9)

Ultraviolet light is used for a photo-electric effect experiment on cadmium. For a given photon wavelength, the energy of the most-energetic emitted electrons is measured to be 8 eV. The experimenter doubles the wavelength of the ultraviolet light and measures a different electron energy:

a) For the zeeman effect what is generally the shape of the magnetic field between the pole pieces of the electromagnets and what effect might the shape of the magnetic field have on the results of this experiment?
b) How would the interference pattern observed for the normal Zeeman effect (eg with a cadmium lamp) differ from the anomalous Zeeman effect transition?

Calculation, Chrimatrographic, and Spectral Applications Experiment:

1. Based on the listed atom economy, experimental atom economy, and “E” product given, what do these values indicate about the efficiency of a dehydration reaction? (Use correct units).

-The atom economy for the reaction was 82.37%.

- The experimental atom economy was 82.40%.

- The “E” product was 70.00

1. In this experiment we injected the sample to be analyzed by Gas Chromatograph equipped with an FID (Flame Ionization Detector). The detector ionizes the sample as it reaches it, and the peak is proportional to the number of ions with a live flame. Explain in detail, why we need to run a standard when the GC is equipped with an FID detector to identify the component in a sample?

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.

Refraction
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

6. Why do you think the inside of a car feels so much warmer than its surroundings on sunny days? a. How can you use the sim to test your ideas? b. Describe your experiment and state some evidence that explain the different temperatures on a microscopic level using photons.
