Ap Statistics Case Study

Median: 3, 5, 11, 12, 13, 15, 19, 35, 42, 65 = 13 + 15 = 28/2 = 14

The mean for the column “mean” is 3.56. It is very close to the parameter of interest but is not equal to it. You can calculate a confidence interval for the mean of the mean column, but a specific confidence interval would need to be provided. In that case, the confidence interval would be centered on 3.56, not 3.5.

| Target # of Passengers = Fixed Cost + Target Profit/ Unit Contribution Margin = 3,600,000 + 1,071,428 / (Selling Price – Variable Cost Per unit) = 4,671,429 / (205 – 85) = 4,671,429 / 120 = 38,928.57

There is no state that has designated the Eastern Red Cedar as its state tree.

Joel has done excellent work with all of the topics we’ve studied. He missed quite a few days of school this semester, but managed to keep up with the material very well. Joel has a very organized and methodical approach to his work. His serious attitude makes him a good candidate for taking on the challenge of AP Statistics next year. I look forward to working with Joel the rest of the semester.

I conducted a survey, asking 20 females and 20 males their favorite food group for my AP Statistics project. I surveyed on Wednesday, September 27 and on Thursday, September 28 at Marshall High School. They chose from protein, grain, vegetables, fruit, and dairy. From the data, I found that 10 males and 2 females liked protein best, 3 males and 2 females liked grains best, 1 male and 1 female liked vegetables best, 3 males and 13 females liked fruit best, and 3 males and 2 females liked dairy best. Half of the males liked protein best, while most females liked fruits best. The least amount of both males and females liked vegetables. From this data, we can see that males like protein more than females do, and females like fruit more than males

After you estimate the average ticket price for all ticket types combined (which is $22.12 for the situation depicted in Exhibit 2), estimate the price for each type of seat (i.e., in Exhibit 2: A-$36.29, B--$22.22, C--$11.31, D--$4.92). [Hint: assume the sales mix for A, B, C, and D seats remains the same as the mix in the Flash Report (Exhibit 2).] $30,000 / (1-0.40) = 7000 ($13.09 - $3.05)

Due to financial hardship, the Nyke shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes – regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are below:

I go to Thornapple Kellogg High School in Middleville, Michigan. Everyone here is usually pretty kind, but there is one person who has helped me excel with my learning and that is my AP statistics teacher Mrs. Wilkinson. Mrs. Wilkinson is a lot more caring than she appears. She really idolizes about her students and how they learn. Mrs. Wilkinson always asks us how our lives are going and what we want to do. She loves to connect with her students on a personal level and is interested in our well being. Her teaching methods always connect with something that she knows we’ll understand. Although she may not seem like the most heartwarming teacher, but she really cares about our well-being.

Josh is handling his first experience in an AP level math course very well. He is focused during class and participating fully, as evidenced by his perfect practice set and notebook grades. Josh is doing his reading and has perfect reading quiz grades. He is still getting the hang of how questions need to be answered on tests, where the words you write are just as important as the numbers you get in your calculations. Overall, Josh is off to a good start in AP Statistics. I appreciate his effort and am enjoying having him for a student again this

Total ticket revenue derived from option A is $3,102,584,407, option B $3,105,798,328, and option C $3,083,901,851.

(Refer to original data.) Fuel cost is a significant variable cost to any railway. If crude oil increases by $ 20 per barrel, it is estimated that variable cost per passenger will rise to $ 90. What will be the new break-even point in passengers and in number of passenger train cars? Then, proceed to compute number of passengers =?

My theory should indicate a higher level of survival amongst the younger age group, but this is not conclusive in Figure 5. I thought that the fare price might indicate a children’s price and therefore allow me to fill in an age, but the fare price doesn’t seem to have much pattern. Another idea I thought might help would be to look at the names of passengers, i.e. miss might signify a lower age. (In 1912 the average age of marriage was 22, so anyone with title miss could have an age less than 22.) Names which include master might indicate a young age as well. Figure 5 also indicates possible outliers on the right hand side.

The mode is the number occurring most frequently in the distribution. The results are: 19, 22, 23, 23, 23, 24, 27, 30, 32, 47. Therefore, the mode is 23.

Since 1987, managing the three-way tensions of ensuring profitability and acceptable quality had been the job of the Public Transport Council (PTC), which regulates transport fares for both buses and trains. In today, according to ‘Fare Review Mechanism Committee Final Report (2013)’ (Anon., 2013) the PTC implements a cap on annual fare adjustments which is based on the formula.
