Iced tea On Tuesday, the bottles of Arizona Iced Tea filled in a plant were supposed to contain an average of $20$ounces of iced tea. Quality control inspectors selected $50$bottles at random from the day’s production. These bottles contained an average of $19.6$ ounces of iced tea. Identify the population, the parameter, the sample, and the statistic.

We need to identify the population, the parameter, the sample, and the statistic.

Individuals that seek to collect information are present in the population.
A sample is a portion of the population from whom data was gathered.
The sample is seen to be the $50$ bottles chosen at random from the day's production, whereas the population must be all bottles from the day's production.
A statistic is a descriptive measure for a sample, whereas a parameter is a descriptive measure for a population.
The average of $19.6$ounce is based on $50$bottles in the sample, and so $19.6$ounces indicate the sample mean weight of the iced tea, implying that $19.6$ is a statistic.
The population minimum temperature becomes the associated parameter.
Statistic :

$\overline{x}=$sample mean weight of the iced tea $=19.6$ ounces
Parameter : $\mu =$ population mean weight of the iced tea
