Business analytics MBA- There are a number of learning scenarios or types of learning algorithms, that can be used depending on whether a target variable is available and how much labeled data can be used. These approaches include supervised, unsupervised, and semi-supervised learning. Explain the difference between each type of machine learning. Give an example of how each is used. Write your responses in detail with examples. Be sure to identify the source of your example in your posting. Your initial post should be of minimum 300 words.

A)In a certain state's lottery, 40 balls numbered 1 through 40 are placed in a machine and eight of them are drawn at random. If the eight numbers drawn match the numbers that a player had chosen, the player wins $1,000,000. In this lottery, the order in which the numbers are drawn does not matter.

Compute the probability that you win the million-dollar prize if you purchase a single lottery ticket. Write your answer as a reduced fraction.

1. PP(win) =    

A single lottery ticket costs $2. Compute the Expected Value, to the state, if 10,000 lottery tickets are sold. Round your answer to the nearest dollar.

C)Suppose a jar contains 8 red marbles and 38 blue marbles. If you reach in the jar and pull out 2 marbles at random, find the probability that both are red. Write your answer as a reduced fraction.

Thank you :)

1. Assume I won 50 million dollars in a lottery that pays installments of 10 million dollars a year for five years or a lump sum of less than 50 million dollars. If I take the installments, my first installment would come the day I claimed my winnings at the state lottery office. If I take the lump sum, I would receive that payment the day I claimed my winnings at the state lottery office. Assume that the interest rate is 5% per year. Calculate what the lump sum should be so that it would exactly equal the stream future installments. You must show and explain your work to be given credit for this assignment.

2. What would your answer change be if the first installment in the question above did not come until one year after I claimed my winnings. You must show and explain your work to be given credit for this assignment.

estimate the weighted average cost of capital, listing the necessary inputs at the top of your sheet, calculate Boeing’s cost of equity and beta.

2. use the capital asset pricing model to estimate Boeing’s cost of equity, assuming 3.5% risk-free rate and 5.5% market risk premium. Link to a separate sheet with beta estimation.

3. where you estimated Boeing’s beta, using historical prices with WEEKLY frequency for the most recent 5 YEARS. Use the SLOPE function to estimate beta. Insert a scatter chart that shows the trendline from regressing returns of BA on the VFINX returns, displays the estimated equation, and the R-squared (check the boxes to display the equation and the R-squared).

4. In the context of your regression analysis shown on the chart, using the specific numbers that you estimated. Explain the meaning of the slope coefficient from the estimated equation and discuss what your estimate implies about the risk of holding BA stock. Explain the meaning of the R-squared from the estimated equation.

Finally, Is Boeing’s cost of equity smaller or larger than Boeing’s cost of debt? Is that what we would expect? Explain!

Consider a monetary intertemporal model we introduced in Part II of Money section. Consider a shock to the economy we studied in Chapter 13 as the likely driver of the business cycle, that is a persistent shock to the producitivity parameter of the economy.

a. Suppose that the central bank fully controls money supply and keeps it constant. What would be the impact of a persistent productivity shock on the price level in the economy? Would you expect the price level to be pro-, counter- or acyclical? Explain your answers, illustrate them with graphs if necessary.

b. Now, suppose that the central bank controls only the monetary base, but the money multiplier is procyclical. As a result, money supply aggregates like M1 and M2 expand whenever output expands. How would the price level behave over cycle in this situation? Would your answer from part a) change? Explain and illustrate your answers with graphs if necessary

Use proper spelling, grammar and sentence structure. A suggestion is given about the number of paragraphs needed but you may write more. You may use quotes but don’t overuse them as putting the author’s ideas in your own words is key to the learning process and will help you remember. If you do use a quote put the page number in brackets right after the quote.

1) BEACH VACATION (5 pts)

You take your family on a wonderful, relaxing vacation to the beach. About 15 minutes after you’ve settled into the perfect spot in the sand, your oldest child tells you he’s bored. To keep him busy you tell him to collect some shells, because you read online that the beach where you’re staying is known for having lots of different colors of shells wash up on the beach. A few days later he’s collected over 500 shells, and he tallies up how many of each color he has in the table below. You’re curious if his collection of shells has the same distribution of colors as the overall beach has, so you go online and find the distribution of shell color percentages you should expect to find at that particular beach, and add those to your data table. Perform a hypothesis test to determine if the color distribution of your son’s seashell collection is what you’d expect at that beach. Use α = 0.10.

Step 1) How would you run this test in MINITAB (Menus, Functions used)?

2) (10 point question) Many people love colorful and tasty tomatoes and an ambitious student in horticulture wants to breed such a tomato variety. He searched all the available tomato genetic resources, and found the two inbred lines he needed. One line produces the tomatoes with a colorful red-green-yellow mosaic pattern (rrTT), and the other strain is 'very tasty' (RRtt).

When the student crossed the two strains together, he made the following observations:

In the F1 generation, all the ripe tomatoes have a regular red color and a regular flavor. The student tasted tomatoes from over 40 individual plants, and was sick with regular tasting tomatoes.

In the F2 progeny, the student sampled 1000 tomato plants: 498 had red-color tomatoes with normal taste, 248 colorful tomatoes with normal taste, and 254 red-color tomatoes with great taste. He was disappointed not to find any colorful tomatoes with great taste. He then sampled another 2000 F2 plants: 998 had red-color tomatoes with normal taste, 511 colorful tomatoes with normal taste, 488 red-color tomatoes with great taste, and 3 colorful tomatoes with great taste; he was so happy to find what he wanted!!!

Based on these experimental results, he realized that the alleles he needs are recessive and the two genes are linked.  

C) (2 points) The tomato genome has now been sequenced and genes on the chromosome are in the following order OPQRSTU. The respective physical distances on the chromosome between these seven genes are very similar. But we now know that there is a 'cold spot' between genes RT and 'hot spots' between PQ and TU. Draw a representation of the genetic map relative to the physical map (both maps are needed here) for this part of the tomato genome. Show the relative (approximate) locations of the genes on the two maps.

D) (2 points) What can you predict about the chromosome chromatin structure between the R and T genes?

Please compelete long detailed answer and be specific please draw graphs with your answers of available, but they are not required. If you use graph, you can also explain what information you want me to get from the graph. Please Limit all answers upto words of 300.
