8*6=48. 8*7=56. So the highest multiplication you can go without exceeding the value of 52 is 8*6. You then need to subtract 52 by 48 to find the remainder. 52-48=4. So the answer would be 48 remainder 4
This will be your formula:
cross multiply (32 times x) (120 times 800)
this is what you'll get:
Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 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)
