The effectiveness of a sleeping drug

 

Determine the effectiveness of a sleeping drug, 75 people were randomly selected; 25 were randomly assigned to take the drug, 25 were randomly assigned to take the placebo, and the other 25 did not receive any treatment. The time to fall asleep after going to bed was measured for the three groups. The data are available on GAP under the “Supplemental Material” folder. Enter the data into SPSS and then answer the questions that follow.
You want to conduct a one-way ANOVA to examine if there is a statistically significant difference at a 5% level between the average time to fall asleep of the three groups.
Clearly state your research questions and state the null and alternative hypotheses in the proper conventional format. Define any symbol that you use to state your hypothesis.
Identify the independent (factors) and dependent variables.
Report your results and state your conclusion regarding the hypotheses.
Interpret the F and p values.
What is the real-life implication of your Step 3 results?
What are the assumptions of a one-way ANOVA? Do the assumptions hold for the data used in this exercise?

Sample Solution

Around 1914, the Germans got their hands on the machine gun plans. They first designed the machine gun after they faced one in a German war. The Germans gave two machine guns per battalion group in their military.(Duffy, 2009) Although they didn’t start doing this until around 1915, when the british started doing the same.

The Thompson Submachine Gun or Tommy gun(see appendix L), was invented by General John T. Thompson. This was the first hand held machine gun ever. Thompson wanted to create the Tommy Gun to try and end the First World War. But the first shipment landed in Europe the day after the war on November 11, 1918.(Bellis, 2015)

In 1930 the Italian army made the Breda Modello 30.(see appendix M) British armies created the Bresal Light Machine Gun(see appendix N) in 1940. The ALFA 44(see appendix O) was created in 1944 by the Spanish military. The AAT-52(see appendix P) (Arme Automatique Transformable) was introduced to military in 1952 by the French army. In 1979 the Italian military made the Beretta AS70 LMG assault rifle.(see appendix Q) Then the American military made the Ares Defence Strike 5.56(see appendix R) “Advanced Weapons System” in 2002. Then in 2012 the American military made the Ares Defence Ares-16 Small Arms Family.(see appendix S) (Staff, 2015)

Since gunpowder has been invented by the Chinese, the whole world has altered it, improved it, and used it for good and bad. They have been used not only for guns but for many other items. Like for fireworks, they use gunpowder as well. Bombs of course use gunpowder for their base of explosion. There are many other iem that use gunpowder but those are just a couple. If only there were more responsible people in the world that wouldn’t use it against us.
