Answer:
(820 ; 980)
Step-by-step explanation:
Given :
Sample size, n = 80
Number of bilingual from sample = 36
Sample proportion, phat = x / n = 36 / 80 = 0.45
Margin of Error = 4% = 0.04
Interval = sample proportion ± margin of error
0.45 ± 0.04
(0.41 ; 0.49)
(0.41 * 2000 ; 0.49 * 2000)
(820 ; 980)
The half life is 138 days, meaning exactly half of the material will decay after this time. Use this information to find the decay factor 
:
Then after 250 days, there will be
grams left.
