1) The applicable formula is
  I = Prt
  I = $30,000×0.095×(120/365)
  I ≈ $936.99

2) The same formula applies.
  I = $30,000×0.095×(85/365)
  I ≈ $663.70

3a) The interest due on day 30 is
  I = $30,000×0.095×(30/365) ≈ $234.25
so the new balance is $30,000 - $10,000 + $234.25 = 20,234.25

3b) The amount due on day 85 is
  A = P(1 + rt) = $20,234.25·(1 + 0.095·((85-30)/365))
  A = $20,523.90

  • 50 adults (the ones that were surveyed)

c. Identify the parameter of interest in the study.

  • the parameter of interest is the people that believe that coffee shops are overpriced

d. Find and interpret a 95​% confidence interval for the parameter of interest.

z score for a 95% confidence level = 1.96

margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579

95% confidence level interval:

0.4 - 0.13579 = 0.26421

0.4 + 0.13579 = 0.53579

  • 95% confidence interval (0.26421 , 0.53579)
