For it to triple its weight, it would need to be 300 grams. It already starts off with 100 grams, and so it needs to gain at least 200 grams in x days. If it gains 8 grams a day, we can calculate the number of days it takes to gain 200 grams by dividing. 200/8 = 25. So, it would take the kitten 25 days after its birth to triple its weight.
Answer:
(0.392 ; 0.508)
Step-by-step explanation:
Given that :
p = 45% = 0.45
α = 1 - 90% = 0.1
Zα/2 = Z0.01/2 = Z0.05 = 1.645 (from Z standard table).
Using the relation :
p ± Z0.05*sqrt((p(1-p))/n)
p ± 1.645 * sqrt(0.45(0.55)/200)
p ± 1.645 * sqrt(0.0012375)
p ± 1.645 *0.0351781
0.45 - (1.645 * 0.0351781) = 0.3921320255
0.45 + (1.645 * 0.0351781) = 0.5078679745
(0.392 ; 0.508)
