I presume that the engine operates under a Carnot cycle, which allows for maximum efficiency.
Assuming this, the Carnot cycle's efficiency can be expressed as
where
represents the temperature of the cold sink
and
signifies the temperature of the heat source.
In this scenario, the cold sink temperature is 313 K, while the heat source temperature is 425 K; thus, we can calculate the engine's efficiency as

Response:
The population mean is parameter = 65 c
Explanation:
In the analysis of samples and inferring population behavior, two key elements are essential.
To ascertain the population mean, we typically extract various samples and calculate their average. The average of all these means will serve as an estimate for the population mean. According to the central limit theorem, as sample sizes increase, the average of a sample tends to follow a normal distribution with an estimated mean being the sample mean.
A statistic pertains to a sample, while a parameter refers to the whole population.
In this case, 65 degrees C represents the entire population; thus, it constitutes a parameter.
