Get college assignment help at Smashing Essays Question Hi, I am in unit 5, I am struggling really bad with hypotheses/null hypothesis. this is what I have so far as my question and my HO and HA;How effective are the medication treatments for children with ADHD?(Ho) Behavior of children taking ADHD meds = Behavior of children not taking ADHD meds.(Ha) Behavior of children taking ADHD meds (not equal) to behavior of children not taking ADHD meds.I have rewritten the question as stated in Unit 5, but the other 3 questions in unit 5 I am having trouble with I will post them below;Population(s) and Sample(s): Given your research question and hypothesis above, what would be your population of interest? Describe the sample you might collect, including sampling method and size to conduct your test of hypothesis.Select a Level for Alpha: Select the level of alpha (α) that you would use in testing your hypotheses. Be sure to think about the criticality of committing a Type I or Type II error before just selecting the conventional α = .05. Which type of error is worse, and why?Power and Effect Size:Suppose the effect size of your research study is very large. What does this tell you about your results? If you were not able to reject the null hypothesis and determined that the statistical power of the study was low, what could you do to increase the statistical power if you were to replicate your study?Is there anyone here that can help with with this unit 5?Thank you

The power of sunlight reaching the top of Earth’s atmosphere

Get college assignment help at Smashing Essays Question The power of sunlight reaching the top of Earth’s atmosphere is 1370 watts per square meter. The total amount of power flowing outward through Earth’s surface caused by radioactivity within Earth is estimated to be 3 trillion watts. Which one – sunlight or radioactive heat – is providing more energy to Earth’s surface, and by how much? What does your answer tell you about the relative importance of these two energy sources for life?

Question 1. (1 pt) You measure the average brightness of a Cepheid variable star over a period of time and thus get its pulsation period. This information is used to determine the star’s           a. distance           b. rotation period           c. motion through the Galaxy           d. All of the these.2. What is meant by a “standard candle” and why are they important to our knowledge of the universe?     3. Once the core of a massive star becomes iron, the star no longer has any means of support. This is because        a. neither fusion nor fission of the element iron results in energy being released.        b. the iron content of the core rapidly declines due to radioactive decay.        c. the element iron is so dense that it collapses immediately into a black hole.        d. there is so little iron in the core of the massive star that it cannot support it. 4. Where did the heavy elements on Earth – iron, nickel, uranium, gold, silver, lead, etc. – originate?     23. (2 pts) What is a neutron star? The conservation of _____ ?_____ causes them to stars spin extremely fast.
