Answer

Answer:

B. Not valid. The sample is biased.

Explanation:

Step1: Identify the sample

The sample is 100 randomly - selected households in Arizona.

Step2: Consider the population

The population is all households in the United States.

Step3: Analyze the sampling

Arizona has a dry climate compared to many other states. Households in Arizona may have different umbrella - owning patterns than households in other parts of the US. So, the sample from Arizona is not representative of all US households, making it a biased sample. Thus, the conclusion is not valid.
