Helping my daughter with science fair project. We are using spirometry data from my clinic to see which gender smoking ages the lungs the most. My daughter thinks smoking ages a woman’s lungs the most. However, wouldn’t the null hypothesis be there is no gender difference in lung age?

The study incorporates daily data as well as monthly data of the LuSE All share Index in order to investigate the random walk hypothesis as well as seasonality effects of the Zambian market.
While the variance ratio tests reject the random walk hypothesis for the Zambian market, and as such, support the view of the use of technical trading strategies in order to outperform buyandhold strategies.

Hi, I’m applying for a post as an Assistant Statistician in Northern Ireland. Part of that application involves being tested on “basic statistical and social research concepts”. It’s been 6 years since I graduated with a Psychology degree ans (sadly) most of my statistics knowledge has evaporated. Is there a resource on this site that might prove helpful?

Attractive as this line of reasoning may be in theory, it is unfortunately wellnigh impossible to test it in practice with any degree of academic rigour.Critics of EMHFor about ten years after publication of Fama's classic exposition in 1970, the Efficient Markets Hypothesis dominated the academic and business scene.
Randomness is the lack of pattern or predictability in events
Hi, Leaders, I’m afraid OSHA and farm workers is outside of my area of expertise, so I wouldn’t know where to begin with a study design or variables. Data analysis methods are pretty standard across the board, but it would depend on what your goals are — i.e. identifying specific factors, finding means, comparing means etc. What exactly is your research hypothesis? I would start there.
A Gentle Introduction to the Random Walk for Times …
Sometimes you might not know how long the output will be. For example, imagine you want to simulate some random vectors of random lengths. You might be tempted to solve this problem by progressively growing the vector:
How do you know if your time series problem is predictable
The hypothesis that a stock market price index follows a random walk is tested for the regional stock market of the West African Economic and Monetary Union called the Bourse Régionale des Valeurs Mobilières (BRVM) using the Lo and MacKinlay (1988), the Chow and Denning (1993), and the Wright’s (2000) rankbased variance ratio tests. The tests are applied to daily stock price index over the period January 2, 2002 to December 31, 2004, and all three tests reveals that the null hypothesis of random walk can not be rejected in the BRVM. This result is an indication that the BRVM is weak form efficiency and has various implications for investors and regulators. The first would engage their savings into productive investments opportunities and the second will limit their intervention as securities are fairly priced.
This is a difficult question with time series forecasting
i) State the null alternative hypotheses, explaining your choice.
ii)Calculate the Pvalue
iii)Represent your results on a graph that marks clearly the rejection and non rejection regions. What do you concludes.
iv) Construct a 90% confidence interval around the March sample mean. Comment on the, relative to your conclusion in part (iii)
