The random variable W is Normal, with a mean of 45 ounces and a standard deviation of three ounces.

<h3>How to describe the random variable?</h3>

The given parameters are:

  • Sample size, n = 9
  • Population mean, μ = 5 ounces
  • Standard deviation, σ = 1 ounce

The mean of the 9 apples is:

μ = 5 ounces * 9

This gives

μ = 45 ounces

The variance of the 9 apples is:

σ² = 1 ounces * 9

This gives

σ² = 9 ounces

Take the square root of both sides, to calculate the standard deviation.

σ = 3 ounces

Since, the variable W is normal; the description of the variable W is (b)
