Avogadro's Hypothesis - In trying to correlate Dalton's atomic theory with Gay Lussac's law of gaseous volume, Berzelius put forward the hypothesis that equal volumes of all gases contain equal number of atoms under similar conditions of temperature. However, it was found that e..

In trying to correlate Dalton's atomic theory with Gay Lussac's law of gaseous volume, Berzelius put forward the hypothesis that equal volumes of all gases contain equal number of atoms under similar conditions of temperature. However, it was found that even a fraction of an atom could be..

It was suggested by Emil Fischer in 1894. According to this view, the enzyme molecule operates by chemically uniting with the substrate molecule, forming an enzyme-substrate complex. The enzyme molecule provides a uniquely structured template on which the substrate molecules can become attached an..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substanc..

The mean score on a standardized test is 100 with a standard deviation of 8. A random sample of 48 scores was found to have a mean of 98. State the null hypothesis and alternative hypothesis. => H o : The mean score = 100, H a : The mean score ≠ 100 or H o : The mean score = ..

It is accepted that in the population there is a relationship between the experience and level of income. However, in the sample, the statistical analysis indicates that one cannot reject the null hypothesis at 5% level and thus the null hypothesis is accepted. Identify the type..

What type of decision is reached when the test value of the statistic falls in the critical region when a true null hypothesis is being tested? => decision cannot be determined from the given information or correct decision or type I error or type II error..

What type of decision is reached when the test value of the statistic falls in the non critical region when a true null hypothesis is being tested? => decision cannot be determined from the given information or type II error or a correct decision or type I error..

A standard notebook is supposed to have on an average, 200 pages, with a standard deviation of 2 pages. From a supply of 2500 notebooks, a random sample of 40 notebooks was taken and found that the mean number of pages in the notebook was 197. State the null hypothesis(H o ) and the alter..

In a statistical hypothesis testing, a researcher kept the significance level, α = 0.05. Test result can be analyzed as: => there is a 10% chance of not rejecting the research hypothesis when it is true or there is a 5% chance of rejecting the research hypothesis..
