After reviewing data from a sample, an inference can be made about the population. For example,Find a data set on the internet. Some suggested search terms: Free Data Sets, Medical Data Sets, Education Data Sets. Introduce your Data Set and Cite the Source. What trends do you notice in your data set? Based on the trends and the history of your data set, make a claim. What kind of test (left, right, two tailed) would you have to complete? Explain the steps needed to complete the Hypothesis Test. What is needed?I need a excel sheet to go with the word document with the example and explanation

Normal DistributionOne theory about the daily changes in the closing price of a stock is that these changes follow arandom walk – that is, these daily events are independent of each other and move upward or downward in a random manner – and can be approximated by a normal distribution. To test this theory, collect the opening and closing prices of stocks from for your favorite company or brand.Initial Post:Choose your favorite company or brand and search finance.yahoo.com with that company name and “historical stock prices.” Download the stock history for this company for the past 6 weeks by selecting the appropriate dates and clicking on “Download to Spreadsheet” at the bottom of page.Calculate the daily change in the closing stock prices by taking the difference between the closing and opening price for the day. This is the daily stock change.Calculate the mean and standard deviation of the daily stock changes by running the Descriptive Statistics in Excel Data Analysis. Share the summary table.Consider the mean, median and mode (if it exists). Is your daily stock change distribution right skewed (median < mean), left skewed (mean < median), or symmetric (mean ≈ median)? What other considerations would you look at to determine whether or not this distribution is approximately normally distributed?See Example post.First response: Read a classmate’s response. Consider investing in your classmate’s stock and assume that the daily change is normally distributed. Using Normal.xlsx, your classmate’s mean and standard deviation, determine the probability for the daily change of this stock to have:A decrease of 0.5 point or more (X ≤ -0.5)?An increase of more than 0.5 point (X > 0.5)?A decrease of more 1 point or more (X ≤ -1)?An increase of more than 1 point (X > 1)?See Example post.Second Response: Read a different classmate’s response. Consider investing in your classmate’s stock and assume that it is normally distributed. If you wanted to be 95% sure of what the daily change would be, what range for a daily change would you expect? Use Normal.xlsx.See Example post.
