Suppose you know that you are able to make a free throw 80 percent of the time. However, in a basketball team trials you are being cautious, and you claim to only be able to make 60 percent of shots. You want to convince a coach that you are able to make the shot at least 60 percent of the time. The coach lets you have 20 shots to demonstrate that you can make at least 60 percent of the shots. How many shots do you have to make so that the coach has significant data rejecting the null hypothesis that you cannot make at least 60 percent of the shots? What is the probability that this test will demonstrate to the coach significant data to support your claim to be able to make 60 percent of free throws?

Mass PercentThe mass percent of an element is the element’s percentage of the total mass of the compound. Mass percent can be determined experimentally or from a chemical formula.1. Urea, NH2CONH2; ammonium sulfate, (NH4)2SO4; and ammonium hydrogen sulfate, NH4HSO4, are all common fertilizers. Rank the compounds in order from largest mass percent of nitrogen to smallest mass percent of nitrogen.2. The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2). How many kilograms of chalcopyrite must be mined to obtain 415 g of pure Cu?Express your answer to three significant figures and include the appropriate units.

I noticed that the website took the payment already from my account and that concerned me a little bit. I also came to the website because the question I put in the status bar was a question that had been asked by another student in the past on this website and so the information should be somewhere in your database. It isn’t just answering the question because I can get the answer from the back of the book. I need help with writing out the hypothesis process in APA format. I don’t have my book here for the additional info you are asking and won’t have it until I get home. Maybe we can cancel this as it doesn’t appear to be a benefit at this time for either of us.Problems on t TestsComplete the following Practice Problems found on pages 270 and 307.Practice Problem #8 pg. 270: What is the power of each of the following studies, using a t test for dependent means (based on the .05 significance level)? To complete this question review the chart located on #8 pg. 270.Practice Problem #16 pg. 307: A researcher theorized that people can hear better when they have just eaten a large meal. Six individuals were randomly assigned to eat either a large meal or a small meal. After eating the meal, their hearing was tested. The hearing ability scores (high numbers indicate greater ability) are given in the following table. Using the .05 level, do the results support the researcher’s theory? (a) Use the steps of hypothesis testing, (b) sketch the distributions involved. (c) Does not need to be completed in this assignment. To complete this question review the chart located on #16 pg. 307.

8.

As the result of a chemical reaction, 18.3 g of CO2 gas is produced. Using the ideal gas law, determine the volume of gas produced when the pressure is 1.00 atmosphere and the temperature is 34°C.

PV=nRT    R=0.08206 L/atmos/mol K,  n=moles T in Kelvin 

You answer will be in liters, and to two decimal places

9.

As the result of a chemical reaction, 56.9 g of O2 gas is produced. Using the ideal gas law, determine the volume of gas produced when the pressure is 1.00 atmosphere and the temperature is 31°C.

PV=nRT    R=0.08206 L/atmos/mol K,  n=moles (round) T in Kelvin 

You answer will be in liters, and to two decimal places

10.

As the result of a chemical reaction, 57.1 g of methane CH4 gas is produced. Using the ideal gas law, determine the pressure of the gas produced when the volume is 16.0 liters and the temperature is 28°C.

PV=nRT    R=0.08206 L/atmos/mol K,  n=moles (round) T in Kelvin  You answer will be in atmospheres, and to two decimal places
