According to a Gallup poll, 60% of American adults prefer saving overspending. Let X = the number of American adults out of a random sample

  1. According to a Gallup poll, 60% of American adults prefer saving overspending. LetX= the number of American adults out of a random sample of 50 who prefer saving to spending.
  2. State in the terms of X ~ B (n, p) X~B (50,0.6) x=binomial distribution

Use Exceland show your formula to find the following probabilities:

  1. the probability that 25 adults in the sample prefer saving over spending P(x=25) =0.0405
  2. the probability that at most 20 adults prefer saving
  3. P(x<20) 0.0034According to a Gallup poll, 60% of American adults prefer saving overspending. LetX= the number of American adults out of a random sample of 50 who prefer saving to spending.
