Provide an example that follows either the binomial or Poisson distribution, and explain why that example follows that particular distribution. In your responses to other students, make up numbers for the example provided by that other student, and ask a related probability question. Then show the work (or describe the technology steps) and solve that […]
Can someone help me with this confidence intervals for the mean sigma known? I don’t understand. The formula is E= zsubc * sigma / sqrt n Assuming .05 as your alpha value, make up a problem similar to this one. Make up 36 gas prices for your example. Use price values in your list that […]
The average number of punds of meat that a erson consumes a year is 214.7 pounds. Assume that the standard deciation is 20 pounds and the distribution is approximately normal. Find the probability, rounded t four decimal places, that a person selected at random consumes less than 220 pound per year.

However, the company that manufactures the car claims that the EPA has underestimated the Polaris’ mileage. To support its assertion, the company selects 50 1994 Polaris cars and records the mileage obtained […]
A random person is selected from a group of people. The probability that s/he has a pollen allergy is 0.3. The probability that s/he has a dust allergy is 0.2. The probability that s/he has a pollen and dust allergy is 0.1. A) Find the probability that s/he has none of the two types of allergy. B) Find […]

For this problem, please use the dataset CPS_85_WAGES.txt (located on Canvas course website). The Current Population Survey (CPS) is used to supplement census information between census years. The data contain 534 observations on 11 variables sampled from the CPS of 1985. It is of interest to determine if relationships exist between wages and the rest […]
The relation between y = ideal weight (lbs) and x =actual weight, based on data from n = 119 women, resulted in the regression line y = 44 + 0.60 x Q: The estimated ideal weight for a women who weighs 120 pounds is A) 120.0 pounds
