4). We have price-per-can information for independentsamples of two soup varieties. Assume thepopulations of prices each follow normaldistributions. Find the 99% CI for the differencebetween the two population means. Use df = 20,if needed.

(a)Consider a flight with a seating capacity of 160 seats. This flight is always full and there is a chance to be overbooked. The actual no-show rate (NSR) of the flight is 3.5% and the estimated NSR is 6.3%. If this flight is oversold according to the estimated NSR, what is the number of excess/extra passengers that will show up and there will be no seats for them on the day of departure? (b)Consider a flight with a seating capacity of 160 seats. This flight is always full and there is a chance to be overbooked.

Let p=(12-2x)^2 for 0≤x≤3 be the price at which x hundred units of a certain commodity will be sold, and let R(x)=xp(x) be the revenue obtained from the sale of the x units. For what level of production is revenue maximized?
f there is no seasonal effect on people getting sick, we would expect equal numbers of people getting sick in each season (winter, spring, summer and fall). A student takes a census of students who took Marketing Research in 2019 and finds that of the 280 students who took Marketing Research in 2019, 75 were sick in winter, 65 were sick in spring, 68 were sick in summer and 72 were sick in fall. She wonders if the excess in the winter is an indication that sickness rates are not uniform throughout the year. What is an appropriate H1? a. The number of people getting sick is not equally distributed across the four seasons. b. The observed values equal the observed values. c. The number of people getting sick is equally distributed across the four seasons. d. The expected values equal the expected values.

Every morning, Tania leaves for work a few minutes after 7:00 A.M.. For eight days, she keeps track of the time she leaves (the number of minutes after 7:00) and the number of minutes it takes her to get to work. Following are the results: Time Leaving: 13 14 16 30 20 12 9 17 16 10 16 Lenght of Commute: 27 20 23 45 20 45 20 28 27 23 30 a. Construct a scatterplot of the lenght of commute (y) versus the time leaving(x). b. Compute the least-squares regression line for predicting the length of commute from the time leaving. c. Compute the coefficient of determintion.
In an orchestra, 23 people can play stringed instruments, 21 can play brass, and 15 can play percussion. Further, 9 of the performers can play both strings and brass, whereas 8 can play both strings and percussion. If no one can play all three types of instruments, what are the maximum and minimum numbers of people in the orchestra? (Hint. Consider expressing the numbers in some of the regions of your diagram in terms of a single unknown, say x.)
An analyst in the real estate business is interested in the relationship between the cost of the monthly rent of an apartment and the size of an apartment, in big cities. She gathers data for apartment buildings in 12 cities in 12 different states. In each city, she gets the numbers for at least 5 different buildings and at least 40 apartments in each building. She reaches the following conclusion: the rental cost of a 2-bedroom apartment is 50% more than the rental cost of a 1-bedroom apartment, and the rental cost of a 3-bedroom apartment is 50% more than the rental cost of a 2-bedroom apartment. Based on the paragraph, what is the minimum number of apartments she collected data on? Do you think her sample was large enough to be statistically valid? Based on the paragraph, are there any apartments or apartment buildings that she would have excluded from her study? Do you see any bias in how she selected apartments for her study? Based on the paragraph, is there a positive…
Refer back to Example 5.31. Two cars with six-cylinderengines and three with four-cylinder engines are to be drivenover a 300-mile course. Let X1, . . . X5 denote the resultingfuel efficiencies (mpg). Consider the linear combinationY = (X1 + X2)/2 - (X3 + X4 + X5)/3which is a measure of the difference between fourcylinderand six-cylinder vehicles. Compute P(0 <= Y)and P(Y > 2). [Hint: Y 5 a1X1 1 . . . 1 a5X5, witha1 = 1/2 ,…, a5 = -1/3.]
