-3(2w+6)-4 = -6w -18 -4 = -6w - 22
This means that none of the above is the correct answer choice.
Answer:
<u>Population : all the steaks Tessa can cook</u>
<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>
<u>Sample : two random thermometer readings</u>
<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>
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.
