Question

Tessa is cooking steak for her family. She wants to be sure the steak has an internal temperature of at least 160 degrees Fahrenheit. She uses a thermometer to measure the internal temperature at two randomly chosen places. The minimum reading in the sample is 165 degrees Fahrenheit. Identify the population, the parameter, the sample, and the statistic______________.

Answer 1

Answer:

Population : all the steaks Tessa can cook

Parameter : minimum internal temperature of 160 degrees Fahrenheit

Sample : two random thermometer readings

Statistic : minimum sample reading of 165 degrees Fahrenheit

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

• Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
• Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
• Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
• Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
