Binomial Distribution

merican air flight 2705 from N.Y. to San Francisco has seats for 340 passengers. An average of 7% of the people with reservations do not show up so American Air overbooks by accepting 355 reservations for the 340 seats. We can analyze this system by using a binomial distribution with N=355 and P=0.93 (the probability that a booked passenger does show up.) A.) find the mean number of booked passengers that the airline should expect to show up for a flight? What is the standard deviation? B.) find the probability that exactly 340 passengers show up for the flight c.) find the probability that at least 341 passengers show up for the flight(in this case some passengers will be bumped from th... click for more

Least square regression

1.The following data represent the number of calories per serving and the number of grams of sugar per serving for a random sample of high -fiber cerals. Here are the data to test this claim. Calories, x 200 210 170 190 200 180 210 210 210 190 190 200 Sugar, y 18 23 17 20 18 19 23 16 17 12 11 11 a. Determine the least-squares regression equation from the sample data. b. Compute the standard error of y' c. Compute the standard error of the slope "b" (note y' = a+bx) d. Construct a 95% confidence interval about the slope.

Calculating standard error and least square regression. Data table in gif format.

Refer to the attachment below for accurate data. A doctor wanted to determine whether there is a relation between a male's age and his HDL (so called good) cholesterol. He randomly selected 17 of his patients and determined their cholesterol. a. Determine the least-squares regression equation from the sample data. b. Compute the standard error of y' c. Compute the standard error of the slope "b" (note y' = a + bx) d.Construct a 95% confidence interval about the slope. e. Suppose a 42 year old man vists the doctor's office. What would be a good guess as to the HDL cholesterol of this patient?
