Answer: No it isn’t
Step-by-step explanation:
If you multiply the 3 to the 4c - 1 to get 12c - 3
12c - 3 doesn’t equal 12c - 3c
solution:
a) The population of interest is all the adults
b) The parameter of interest is p, the proportion of adults who own a cell phone
c) The statistic is the proportion, p^, of the sample of 1572 adults who own a cell phone. The value of the sample proportion is 0.83.
d) We dont the the exact proportion with 100 % but we know that the proportion would lie in a certain range with certain degree of confidence
Total sum / number of slopes. That’s the formula for averages
The most accurate estimation of 4+8 is 10
<u>We are given the proportion:</u>
6:n = 8:12
<u>rewriting as fractions:</u>
6 / n = 8 / 12
<u>Solving for n:</u>
6 = (8/12) * n [multiplying both sides by n]
n = 6 / (8/12) [dividing both sides by (8/12)]
n = 6*12 / 8
n = 9
