  • I need some help with Statistics/Probability. Help!?

    The population parameters below describe the full-time equivalent number of students (FTES) each year at Lake Tahoe Community College from 1976–1977 through 2004–2005.

    • μ = 1000 FTES

    • median = 1,014 FTES

    • σ = 474 FTES

    • first quartile = 528.5 FTES

    • third quartile = 1,447.5 FTES

    • n = 29 years

    A sample of 11 years is taken. About how many are expected to have a FTES of 1014 or above? Explain how you determined your answer.

    ***NOTE: I don't quite get what I am supposed to do...so far I guess calculated the IQR which is 919 FTES. After that, I am lost.

  • I need help with this lab question!?

    Explain how internal standard calibration methods can be used to compensate for injector variability in GC (gas chromatography) analysis.

    NOTE: I just guessed that it's because we are still able to get the correct concentration for the sample even though a serious problem was encountered in the sample injection process BUT I have a feeling this is incorrect or something.

  • I need help solving these physics questions!?

    Consider a particle with a charge of of 1.3C.

    a) Find the electric potential at point A, located 1.5m north of the particle.

    b) Find the electric potential at point B, located 2.0 m above the particle.

    c) Would it require extra work to move an electron from point A to B or could the electron do work moving from point A to B?

    d) How much work would be required or released moving an electron from point A to B?

    (Electric potential and work are scalars.)

    ***NOTE: For a) I got 7.7913x10^9 V and for b) I got 5.8435x10^9 V.

    I am having trouble with c) and d) since I am not quite sure how to start them. Thanks!
