Hello, I have an online hw I would like help in. It is about intro to statistics. it is multiple choice, 30 questions

Sample questionÂ

Assume that the null hypothesis is that the population mean is equal to 80 and the alternative hypothesis is that the population mean is less than 80. A random sample of 99 elements selected from the population produced a mean of 75.3. Assume that the population standard deviation is 24.6, and that the test is to be made at the 5% significance level. What is the critical value of z?

approach your life with a mindful sense of discovery

approach your life with a mindful sense of discovery
In this final week, you were encouraged to “approach your life with a mindful sense of discovery and invention;” in other words, to live creatively (Chaffee, 2007, p. 533). Another author quoted in our discussion tells us, “Creativity is a lifestyle, not simply a single activity. Let it expand you” (Trespicio,Body & Soul,2007, p.158). What do you do in your everyday lifestyle that demonstrates your creativity? (Hint: it’s not about drawing or painting or being “artistic.”) How does creativity expand you? Why is creativity an important part of critical thinking?

POL 389 – The war in Iraq that began in 2003

POL 389 – The war in Iraq that began in 2003
The war in Iraq that began in 2003 has been a major event for both the United States and Iraq. 4500 U.S. lives and that of tens of thousands of Iraqis have been lost. After U.S. troop levels dropped to just 500 in2011, 3000 additional soldiers were sent back in 2014 when the Islamic State gained control of several majorIraqi cities. Given the rationale stated at the beginning of the war by the Bush administration and subsequentjustifications for staying there, has the war been worth its cost in lives and money.

Abstract: The Bychkov model of extremely fast flame acceleration in obstructed
pipes [Combust. Flame 157 (2010) 2012] employs a number of simplifying
assumptions, including those of slip and adiabatic surfaces of the obstacles and of
the pipe wall. In the present work, the influence of various mechanistic surface
conditions on the flame dynamics in a cylindrical pipe of radius R, involving an
array of parallel, tightly-spaced obstacles of length aR, is scrutinized by means of
the computational simulations of the fully-compressible axisymmetric
hydrodynamic and combustion equations with an Arrhenius chemistry.
Specifically, nonslip and slip surfaces are compared for the blockage ratio, a and
the spacing between the obstacles, ?z, in the ranges 1/3 = a = 2/3 and 0.25 = ?z/R
= 2.0, respectively. It is shown that the impact of surface friction on flame
acceleration is minor, only 1.3~3.5%, being positive in a pipe with ?z/R = 0.5 and
negative for ?z/R = 0.25. We have also demonstrated a minor effect of the
isothermal surfaces as compared to the adiabatic ones [Phys. Fluids 28 (2016)
093602]. With the fact that the real boundary conditions are neither slip nor
nonslip; neither adiabatic nor isothermal, but in between these categories, the
present work thereby justifies the Bychkov model and makes its wider applicable
to the practical reality. While this result can be anticipated and explained by the
fact that the flame dynamics is mainly driven by its spreading in the unobstructed
portion of an obstructed pipe (i.e. far from the wall), the situation is, however,
qualitatively different from that in the unobstructed pipes, where the mechanistic
and thermal wall conditions modify the flame dynamics conceptually.
Keywords: computational simulations, obstructed pipes; wall friction; boundary
condition.
