Station 1. You have run an experiment studying the effects of the molecular weight of a compound on the rate of diffusion in agar. Compound X has a molecular weight of 25.3 g/mol and compound Y has a molecular mass of 156.2 g/mol. On two separate agar plates, 0.1 g of each substance were transferred and allowed to diffuse for 2 hours. The results below were obtained. Use this information about this situation to answer the following three questions. 1. Question: (CO 1) What was the independent v...

AQA AS-LEVEL PHYSICS 7407/1 PAPER 1 JUNE 2022 QUESTION PAPER. A sample of bromine gas contains a mixture of two isotopes. An experiment is done to find the percentage of each isotope in this sample. 0 2 . 1 In the experiment, the gas is ionised by a beam of electrons. Explain how the beam of electrons causes a particle of the gas to have a charge of +1e. The gas consists of bromine molecules. Each molecule has two bromine atoms. The experiment finds that the bromine molecules contain 158,...

Explain what we mean by a confidence level (exp. 95%) The percentage of intervals, based on all possible samples of the same size taken from the same population, that contain the parameter. For example, if we construct 100 95% confidence intervals using 100 samples of the same size, approximately 95 of the intervals will contain the true parameter and 5 will not. A point estimate is the value of a _________ that estimates the value of a ____________ statistic, parameter ...
