valkas [14]

Answer:

c. The sampling distribution of the sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed

Step-by-step explanation:

From the given data, we have;

The category of the sample = Retired individuals

The number of participants in the sample = 20

The duration of program = six-weeks

The improvement seen by most participants = Little to no improvement

The improvement seen by few participants = Drastic improvement

Therefore, given that the participants are randomly selected and the majority of the participants make the same observation of improvement in the time to walk a mile, we have that, the majority of the outcomes show little difference in walk times after the program, therefore, the distribution of the sample data is not skewed and can be assumed to be approximately normal

Problems 1-8, name the sets of numbers to which each number belongs.
posledela

The name of the sets of the numbers to which each of the given number belongs is:

  1. 7 = Natural number. Integer. Rational number.
  2. √23 = Irrational number.
  3. л = Irrational number.
  4. O = Rational number. Integer.
  5. -0.5 = Rational number.
  6. -2.5 = Rational number.
  7. √0.09 = Rational number.
  8. -√0.9 = Irrational number.

<h3>What are sets of numbers?</h3>

These are the various types of number groups that exist for categorizing numbers.

Natural numbers are all positive numbers from 1 to infinity while integers are positive and negative whole numbers. A decimal cannot be an integer as a result.

Rational numbers are discrete which means that they are terminating and eventually stop going while irrational numbers will keep going to infinity and are therefore non-terminating.
