4 0

The proportion of field mice weighing more than 33 grams in the distribution will be about 0.2275

  • Mean, μ = 25 grams
  • Standard deviation, σ = 4 grams
  • Score, X = 33 grams

We need to calculate the P(Z > Zscore)

Recall :

Zscore = (X - μ) ÷ σ

For X > 33 :

Zscore = (33 - 25) ÷ 4 = 2

Therefore, the probability would be expressed as :

P(Z > 2) = 1 - P(Z < 2)

From the normal distribution table :

P(Z < 2) = 0.97725

Therefore,

P(Z > 2) = 1 - 0.97725 = 0.02275
