Abstract Abstract This practical was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed

After careful review of the results and analysis of the execution of the lab‚ I have determined the following examination of errors that affected the outcome of my group’s lab. First and foremost‚ the golden metal [brass] trials appear to be free of major flaw. The density results of the golden metal trials are precise‚ all occurring between 8.1 and 8.7 grams per cubic centimeter

The objective of performing this test is to test if the factory equipment accounts are materially overstated from the errors found in the capitalization of ordinary repairs. The sampling unit is the debit posting to the factory equipment account and the population is $12‚600‚000 which is the difference between the total debits of $89‚860‚000 and the equipment additions

(Linear in Parameters) – From observation of equation (2) we can see that the model in the population can be written in the form y = β0 + β1X1 + …+ βkXk + u. In the model β1‚ β2 …βk are the unknown parameters of interest and u is an unobserved random error. log(TCi) = β1+ β2log(Qi) + β3log(pi1) + β4log(pi2) + β5log(pi3) + ui (2) MLR 2 (Random Sampling) – This assumption assumes a random samples of n observations. We deduce that it would be infeasible to collect the entire population of observations

Determine sample size ▪ Slovin Formula: ▪ n = N__ ▪ 1+NE² ▪ Where: n = sample size ▪ N = population size E = margin of error * desired Example: What should be the representative sample size if the population from which the sample will be taken is 10‚000 and the desired margin of error is 2%? Solution: To determine the sample size‚ use the formula; n = ___N__ 1+NE² n = 10‚000 = 2‚000

Introduction Peer reporting is an important thing to think about in the health care profession due to the severity of the possible outcomes when something is not reported. If a medication error has occurred‚ it could mean life or death to the patient‚ depending on the situation. Often‚ something worth reporting goes ignored to “keep the peace” at work‚ but could also put patients safety at risk. Another factor if something goes unreported is when a friendship is involved. A dilemma workers face
