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)
