In an initial simulation, a small population of six snails (out of 85) founded a new population. Suppose 50 snails from the original site. (rather than six). Assuming these 50 snails survived and reproduced on the new island, what effect would the larger sample size have on the result? Could you predict any shifts in the gene pool due to random genetic drift?

Now consider the two populations of snails living on a single island. Is it at all plausible that these populations might become reproductively isolated? If reproductive isolation does occur, describe some long-range consequences that you might expect to observe in snail populations. If speciation were to occur on a single island, what types of adaptations might you expect to evolve in the WTSP predator population?

There is a hill 600 feet tall the slope of the road originally has a 27% grade(slope) and it is decreased to 14% to make it a legal road in the town. legal roads have a 12-15% grade maximum. Find the length of the new road and the percentage increase between the old and new road

Smart Science School is a new private primary school that is established in Sohar, and its automated system is not yet in place. The school has identified three significant registration process which includes: a) Information where inquiries are answered, and forms are distributed where estimated time could be from 2 minutes to 15 minutes; b) Assessment where the forms are submitted, and the cost will be calculated with an estimated time of 5 minutes; c) Payment where the calculated amount will be paid, and cash receipts will be given and are expected to be 3 minutes. There are 3,500 students, and it is expected that at any given time, the expected influx of customers to be 75. The school is open for 8 hours a day. a) Design a floor plan which also illustrates the registration process, why that is the most appropriate design for the school. b) Identify and justify which service discipline that you intended to follow by mentioning the possible problems or challenges that will be avoided. c) Identify and justify the appropriateness of the structure (systems) of the waiting line situation. d) Based on your answer in letter c, explain the process of how the structure of the line situation will work. e) How many employees for each process you need to ensure all customers will be served. justfy

) A public school district is investigating whether to purchase a new school bus to take over the rural-most route in the district. They have two options:

A modern, eco-friendly bus complete with seat belts and air conditioning, will have a first cost of $95,000, cost savings (in terms of fuel efficiency and maintenance costs) of $20,000/year the first year, and decreasing by $1000 per year thereafter (so $19,000 the second year, 18,000 the third year, etc…). It’s estimated that the salvage value will be $8,000 at the end of its 20 year life.

A more basic bus will have a first cost $70,000, cost savings of $14,000 per year decreasing by $500 per year each year thereafter (so $13,500 the second year, $13,000 the third year, etc.).It is estimated that the salvage value will be $5000 at the end of its 20-year life.

Assume that the school district also has the option to stay with their current fleet (so the do nothing option is also available).

A) Use Benefits to Costs analysis to determine which of the options, if any, would be most economical for the school district if their MARR is 5%.

B) Compute the value of X- i.e., the first cost of the modern bus- that makes the two alternatives in this example equally desirable:

C) In this problem only the economic consequences were evaluated. Do you think this type of decision is only economic, or are there other factors that could/would/should be considered? Briefly discuss…

1. A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the school's students, 32% of them plan to go into general practice. Find the P-value for a test of the school's claim

2. In a sample of 47 adults selected randomly from one town, it is found that 9 of them have been exposed to a particular strain of the flu. Find the P-value for a test of the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.

3. An article in a journal reports that 34% of American fathers take no responsibility for child care. A researcher claims that the figure is higher for fathers in the town of Littleton. A random sample of 225 fathers from Littleton, yielded 97 who did not help with child care. Find the P-value for a test of the researcher's claim

4. An airline claims that the no-show rate for passengers booked on its flights is less than 6%. Of 380 randomly selected reservations, 18 were no-shows. Find the P-value for a test of the airline's claim.

5. Find the P-value for a test of the claim that less than 50% of the people following a particular diet will experience increased energy. Of 100 randomly selected subjects who followed the diet, 47 noticed an increase in their energy level

Your Uncle Paulie comes to you seeking advice on how to pay for college tuition for his two boys, Ivan who is 2 and Martin who is 6. He is set on Martin going to his alma mater, where tuition is currently $40,000. He wants Ivan to attend a local public university for 2 years, travel abroad at Ivan’s expense, and then finish his last two years at the local university. Tuition is currently $30,000. Because of the difference in cost, Uncle Paulie will cover 3 years for Martin and 4 years of tuition for Ivan. He anticipates school costs will rise 4% annually and feels he can achieve 15% annually. How much should he set aside and invest today in order to meet his funding goals?

Suppose in Karachi the first sushi restaurant opens in town. Initially, people hesitates and are
extremely cautious to try a raw fish, as in our town people loves chicken, mutton and meat.
In which, grilled meat in different forms of food have always been popular. Soon, however,
WHO - health report warns people against grilled meat and suggests to increase their
consumption of fish, especially raw fish. Slowly and gradually, the new start up business of
sushi becomes very popular and its profit increases.
