Solve the following questions using classical probability theory. If a particle is identified by HiggsView as a Higgs boson, what is the probability that it actually is a Higgs boson?
Classical Probability Theory Question 1) Solve the following questions using classical probability theory. Show your math or describe your answer clearly. Given P(A) = 0.6 ; P(B) = 0.5; and P(A ⋂ B) = 0.2 , then P(A|B) ? If P(A) = 0.3 and P(B|A) = 0.3, are events A and B independent? If not […]
Suppose that n = 200 voters are randomly sampled from the large number of voters in this area, what is the probability that at most 60 voters favor the bond issue?
Probability A pollster believes that 25% of the voters in a certain area favor a bond issue. a) Suppose that n = 200 voters are randomly sampled from the large number of voters in this area, what is the probability that at most 60 voters favor the bond issue? b) How many voters should be […]

Calculate the coefficient of determination. Determine the regression equation. Is there a positive association between the size of the house and its selling price?
Correlation coefficient 1-A sample of 12 houses that were sold last week in San Juan is selected. Can we conclude that, as the size of the house (reported in thousands of square feet in the table below) increases, so does the sale price. The following table in thousands of square feet), the selling price (reported […]
Compute the unweighted aggregate price index. Determine the actual percentage growth between the base period and the tenth period in your data for each item.
Case study As a group selects a recent case study with time series price data that includes two or more items to be analyzed. You can use data from your area of specialization and excel software. Use a sample size, which is not more than 15 and not less than 10 observations. After reading section […]
Calculate the predicted adult children’s height whose parents are “tall” after 1, 2, 3, …, Z generations? And similarly, what is your prediction for adult children’s height whose parents are “short” after 1, 2, 3, …, Z generations?
