Tanya is playing PokemonGo, and searching for a Snorlax. The game is programmed such that pokemon are generated randomly, and there is a 7% chance that a Snorlax will appear. Tanya will search Mill Creek park until she captures 473 random pokemon. Consider the proportion in her sample that will be Snorlaxes. As we have learned, the sample proportion is a random quantity.

What type of random variable can we use to approximate the sample proportion? Type the name of the distribution using all capital letters.

What is the mean of the sample proportion? Input your answer as a decimal, not a percent.  

What is the standard deviation of the sample proportion? Input your answer as a decimal, not a percent.

What is the approximate probability that more than 6% of her sample will be Snorlaxes? Input your answer as a decimal, not a percent.

The Cash account of Guard Dog Security Systems reported a balance of $2,540 at December 31​, 2024. There were outstanding checks totaling $400 and a December 31 deposit in transit o f$100.

For this week's discussion, the focus will be on examining Porter's Five Forces as a tool for looking at the pressures on profits. Specifically, you will be looking at defining Porter's Five Forces and applying this tool to the market structures and pressures on profits of a chosen group of firms.

Instructions

In your discussion post, address the following:

• Chose one of the following groups and use Porter's Five Forces to analyze the pressures on profits for your chosen group's firms.
  • Group 1: the accommodations industry (e.g., Hilton, Marriott Bonvoy, InterContintental Hotel Group).
  • Group 2: the wireless telecommunications industry (e.g., Verizon, AT&T, T-Mobile).
• If you want to dig deeper into how one of the firms views the challenges it faces, you might want to look at the firm's investor page.

2.(a) Ball A is released from rest. It collides with the stationary ball B with a velocity 3.2 m/s; immediately after the collision ball A travels in the same direction with velocity 2.3 m/s.   

Ball A has mass 0.26 kg; ball B has mass 0.07 kg.

Calculate

(i) the velocity of ball B immediately after the collision..

(ii) the maximum height reached by ball B.

(b) A driver is travelling at a constant speed of 15.4 m/s in a 1800 kg car.

At this speed he then enters a large empty car park, and makes a U-turn, travelling in a complete half-circle of radius r.

The friction force between the tyres and the ground is 12.4 kN.

Calculate r.

In the case Las Vegas Sands v. Nehme, reported on page 380 of your textbook, the casino's "marker" was found by the court to be a negotiable instrument. The Venetian (a hotel owned by Las Vegas Sands LLC) was then allowed to sued Nehme for not paying a negotiable instrument. In a 500 word paper discuss the required elements for a negotiable instrument. Is it feasible that the casino marker contained all of these elements? Explain whether or not you think that gambling casinos should be able to advance credit to gamblers. From what you know about how alcohol affects a person's capacity to contract, is the fact that most gamblers are also consuming alcohol a factor in your decision? Do you think people would not gamble as much if casinos did not offer "markers?"

1. Juan Martinez was reviewing his recent bank credit card account statement when he found two charges involving a hotel room rental and a meal, purchased on the same day in a city than Juan knew he had not been to. Their charges totaled $229.99 out of Juan’s $529.99 balance for the month.

a. What payment should Juan make on the account?

b. How should he notify the credit card issuer about the unauthorized use?

c. Once the matter is resolved, what should Juan do to ensure that his credit history is not negatively affected by this error?

2. Explain the conditions that might make bankruptcy necessary. How might you use the services of a credit counselor?

A new study was done that included responses from 600 randomly sampled quests, of which 55% said they register using the hotel website. If the true proportion were 50% or less, what is the probability your sample data would produce a sample proportion of 55% or higher? Be sure to set up the two competing hypotheses and provide a statistical conclusion statement at a 2% level of significance for your results.

(Be sure to write out/ calculate how you find X, thank you) (Also, if you know how to find the type 1 error can you explain how you got it?)

2. Using Minitab, repeat the problem. Copy and paste it, please. (can't find it, This is really confusing!)

Identify the sampling method for each scenario.

1. (a) An orchard farmer subdivides his orchard into 40 parcels of land. He randomly selects 4 parcels and inspects every tree on those parcels for the presence of a particular fungus.
2. (b) A librarian inspects every fifth book on a shelf starting with the second to determine the number of items missing bar codes.
3. (c) A hotel leaves customer satisfaction cards in each guest room. At the end of the week, the general manager reads all 60 cards that were filled out by guests that week.
4. (d) The College of Engineering randomly selects samples from each of its four branches (mechanical, civil, chemical, electrical) to assess the effectiveness of a new program for student advising.

The Japanese harvester beetle has infected several forests in the Northwest. Official estimates are that 17% of trees are infected. You are a park ranger who has been seeing a lot of these beetles lately, and you think the rate is higher in your area. You check 400 trees around your cabin and find that 79 of them are infected.

• Go through the steps on the Hypothesis Test Guide (D2L). List each step like Step 1, Step 2, etc.
• Please check the conditions using complete sentences.
• Please do the calculations out the long way, but definitely use GeoGebra or a calculator stats package to check.
• Even if the conditions aren’t met, do the rest anyway.
• Use α = 0.03
