The number of days per week worked by husbands in the United States in the early 1990s had mean 5.2 and standard deviation 0.7. (a) Assuming each husband reported a whole number in answer to the question, "Typically, how many days do you work each week?", the random variable X for number of days worked has eight possible values; what are they? (Enter your answers as a comma-separated list.)

Respuesta :

Answer:

X = {0, 1, 2, 3, 4, 5, 6, and 7}

Step-by-step explanation:

The random variable X is defined as the number of days worked by the husbands of the United States.

In a week there are seven days.

The question asked was:

"Typically, how many days do you work each week?"

A husband can answer to the question asked as 0 days, 1 day, 2 days, and so on till 7 days.

So the values that the random variable X can assume are:

X = {0, 1, 2, 3, 4, 5, 6, and 7}

Thus, the random variable assumes 8 possible values.
