Question 1 of 10

Which sampling method gives every member of the population an equal chance of being selected?

Convenience sampling Voluntary response sampling Simple random sampling Judgment sampling

Question 2 of 10

Which measure of center is most resistant to outliers?

Mean Median Mode Range

Question 3 of 10

According to the empirical rule, approximately what percentage of data in a normal distribution falls within 2 standard deviations of the mean?

68% 90% 95% 99.7%

Question 4 of 10

What does a p-value measure in hypothesis testing?

The probability that the null hypothesis is true The probability of observing data as extreme as the sample data if the null hypothesis is true The probability that the alternative hypothesis is true The probability of making a correct decision

Question 5 of 10

What is a Type I error in hypothesis testing?

Failing to reject a false null hypothesis Rejecting a true null hypothesis Accepting the alternative hypothesis when there is no data Using the wrong significance level

Question 6 of 10

If the correlation coefficient between two variables is r = -0.85, what can we conclude?

There is a strong positive linear relationship There is a weak negative linear relationship There is a strong negative linear relationship One variable causes the other to decrease

Question 7 of 10

The Central Limit Theorem states that as sample size increases, the distribution of sample means approaches what shape?

Uniform Skewed right Normal (bell-shaped) Bimodal

Question 8 of 10

In a binomial distribution with n = 20 trials and p = 0.3, what is the expected number of successes (mean)?

3 6 10 14

Question 9 of 10

Why is extrapolation (predicting beyond the range of observed data) generally unreliable?

It requires too much computation The correlation always becomes weaker outside the data range We have no evidence that the pattern continues beyond the observed range It violates the Central Limit Theorem

Question 10 of 10

Which Biblical principle most directly supports the importance of testing claims with evidence before accepting them?

Love your neighbor as yourself The lot is cast into the lap, but its every decision is from the Lord Test everything; hold fast what is good Be fruitful and multiply
