Again, there is research on the relationship between gender and sense of direction. Recall that, in their study, the spatial orientation skills of 30 male and 30 female students were challenges in a wooded park near the Boston College campus in Newton, Massachusetts. The participants were asked to rate their own sense of direction as either good or poor.

In the park, students were instructed to point to predesignated landmarks and also to the direction of south. For the female students who had rated their sense of direction to be good, the table above provides the pointing errors (in degrees) when they attempted to point south.

1. If, on average, women who consider themselves to have a good sense of direction do not better than they would by just randomly guessing at the direction of south, what would their mean pointing error be?
2. At the 1% significance level, do the data provide sufficient evidence to conclude that women who consider themselves to have a good sense of direction really do better, on average, than they would by just randomly guessing at the direction of south? Use a one-mean t-test.
3. Obtain a normal probability plot, boxplot, or stem-and-leaf diagram of the data. Based on this plot, is use of the t-test reasonable? Explain your answer.

Jane Botosan operates a bed and breakfast hotel in a resort area near Lake Michigan. Depreciation on the hotel is $60,000 per year. Jane employs a maintenance person at an
annual salary of $41,000 and a cleaning person at an annual salary of $24,000. Real estate taxes are $10,000 per year. The rooms rent at an average price of $60 per person per night
including breakfast. Other costs are laundry and cleaning service at a cost of $10 per person per night and the cost of food which is $5 per person per night.

Instructions:

1. Determine the number of rentals and the sales revenue Jane needs to break even using the contribution margin technique.

2. If the current level of rentals is 4,000, by what percentage can rentals decrease before Jane has to worry about having a net loss?

3. Jane is considering upgrading the breakfast service to attract more business and increase prices. This will cost an additional $3 for food costs per person per night. Jane feels she
can increase the room rate to $68 per person per night. Determine the number of rentals and the sales revenue Jane needs to break even if the changes are made.

1) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 63women over the age of 50 used the new cream for 6 months. Of those 63women, 36 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60% of women over the age of 50? Test using ?=0.01

What's the process of each one and result? A singer quartet consisting of Angel, Betty, Carlos and Diana wants to practice their singing. However due to the pandemic they decide to do so at a baseball park to keep social distancing. Angel stands on the home plate, Betty goes to third base, Carlos to second base and Diana to first base. While they are getting ready a bird flies along the line joining third base and home, Betty says “That bird is singing at a frequency of 350 hertz”, but Angel says “No, it is singing at 340 hertz.” Soon after the bird leaves the park Diana sings a 440 hertz note, Carlos hears it 0.1 second later and sings a 261 hertz note. Part a Make a drawing of the bird’s flight path along the line joining third base and home, with an arrow indicating the direction of flight, towards home or away from home. Part b Explain why you chose that direction, include any equations that support your explanation. Part c How far is Carlos from Diana? Show your calculations. Part d What is the period of Carlos’ note at 261 Hertz. Include your calculations

1. On Friday March 10th 2017, around 11pm your instructor Mr. Tamba Yaradouno was at O'Hare International Airport in Chicago picking up a relative. At the passengers arrival what they call "Vestibule" or numbered gates, he could not park and waited for long. The area was packed, airport security cars flashing lights everywhere not allowing anyone to park but just enough time to pick up people.

On Friday October 12th 2018 at about same time your instructor was at the same spot of that airport to surprisingly notice that the area was completely empty and sat there for almost two hours.

a. What has happened to the demand curve of tourists visiting Chicago and the USA in general.

b. What could happened to both demand and supply curves of airport jobs, to the international flights into the USA if this trend of tourists decline continue.

Note: Do not include COVID- 19 here, this is the change of the world view of the USA from the Obama administration compared to President Trump and thus the changes of the number of tourists visiting USA
