1. Assume the room rate for a 3-star hotel in Paris follows a normal distribution with a mean of 175€ and a standard deviation of 16€. What is the probability that a randomly selected 3-star hotel has a room rate of Z(X) = (x-μ)/σ σ=16 μ=175 a) Less than 195 Euros? Z (195) = (195-175)/16 = 1‚ 25 so 89‚ 4% b) More than 180 Euros? Z (180) = (180-175)/16 = 0‚ 31 so 62‚ 2% c) Exactly 170 Euros? Z (170) = (170-175)/16 = - 0‚ 31 so 37‚ 8% d) Between 150 and 182 Euros?

The Scientific Method 1. Choose a problem. (What do you want to explore? Ask a question about it.) * Choose something that interests you. * Choose something that you don’t know the answer to. * Choose something you can work with. Which soda decays fallen out teeth the most? 2. Research the problem. (How can you find the answer to your question?) * Look in books. * Get advice. * Make observations. If you take your teeth‚ put them in a glass‚ pour soda over them and let them stand

fund scientific research? It is incredibly important to examine the question "if science produces such large economic benefits‚ why should governments fund scientific research?" In contemporary society‚ the importance of funding scientific research is quite high since "state funding helped get Google’s search algorithm‚ antibody cancer therapies‚ and DNA sequencing technologies off the ground."(Huppert and Taylor‚ 2013) However‚ it is also equally important to highlight that funding scientific research

A scientist observes that a pond adjacent to an industrial plant has heavier algae growth than ponds farther away (G). I chose this as an example of observation because the sentence explains in detail how the scientist first gathered the idea to for conducting the experiment. 2. Ask a question. A scientist wonders if the waste water emitted from an industrial plant is accelerating

Major Characteristics of Survey Research * Most surveys possess three basic characteristics: (1) the collection of information (2) from a sample (3) by asking questions‚ in order to describe some aspects of the population of which the sample is a part. The Purpose of Survey Research * The major purpose of all surveys is to describe the characteristics of a population. * Rarely is the population as a whole studied‚ however. Instead‚ a sample is surveyed and a description of the population

to treatment to determine their effects on treatment outcomes among minority adolescents. The literature review serves as a starting point for greater attention in research‚ to address the lack of representation minorities have in substance abuse treatment. The research proposal is asking minorities (n=200)‚ through a survey method‚ to answer questions about prior drug education‚ family history and prior access to clinical treatment. The results will show the youths who received both factors will

Algae blooms are due to a rapid increase of algae and too much nitrogen in the water. From this information‚ I can deduce that there is a runoff problem from one or more of the farms where fertilizer

that unknowns #1‚ #2 and #3 are identified correctly. I am certain due to the qualitative data I collected during my observations. Sight‚ smell and texture were the determining factors. C. One of the most important and unique steps in the scientific method is the ability to create a new hypothesis if your results do not support your original ideas. What areas in your life‚ other than in science class‚ do you think this type of step would be helpful? Explain your answer. I believe that life in

It is primarily a methodology used to characterize and quantify specific sources of error that contaminate the observed measurement of interesest in order to have future research be more error free. In other words‚ if something has often happened in the past‚ it will likely happen in the future (Lee & Baskerville‚ 2003). In research that is extremely important because once researchers have collected enough data to support their hypothesis‚ they can develop a premise to predict the outcome in similar
