Answer:
D) If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
Explanation:
Most of this AP question is fluff to confuse you, so make sure to emphasize the p-value and the actual question being asked.
For these interpretation problems, for chi-square GOF (goodness of fit) tests, the p-value is interpreted as such:
If the null hypothesis () is true, there is a [-value] probability of obtaining a chi-square () value of [test-statistic ] or more extreme.
This answer choice fits the format the best, and is therefore the correct answer.
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
