Answer:
Saturated hydrocarbons are relatively unreactive except in the presence of high temperatures and oxygen.
Step-by-step explanation:
we have to choose the option in which saturated hydrocarbons react.
Saturated hydrocarbons do contain double and triple bonds that make molecule reactive. They only contains sigma bonds, which are very stable and difficult to break and hence these are unreactive.
In saturated hydrocarbons the percentage of carbon is lower which gets easily oxidised in oxygen of the air to form completely.
Saturated hydrocarbons are generally unreactive, but when exposed to high temperatures and oxygen they react in a combustion reaction to produce Carbon Dioxide and Water.
Hence, Saturated hydrocarbons are relatively unreactive except in the presence of high temperatures and oxygen.
Option option 1 is correct.

Answer:
c) 72% is a statistic and 56% is a parameter.
Step-by-step explanation:
Previous concepts
A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation
A parameter is "any numerical quantity that characterizes a given population or some aspect of it".
Solution to the problem
For this case we know that they select a sample of 663 registered voters and the sample proportion from these registered voters is:
representing the sample proportion of people who voted in the election
They info that they have is that the true proportion before is and that represent a value related to the population.
So on this case the 0.72 represent a statistic since represent the sample and the 0.52 is a value who represent the population for this case is a parameter.
So the correct option is:
c) 72% is a statistic and 56% is a parameter.
