Sample Question 1
A poll of 1,000 adults reports that 58% support a new policy with a margin of error of ±3% (95% confidence). Which interval best represents the plausible range for true support?

55% to 61%

55% to 60%

54% to 62%

52% to 64%

Sample Question 2
Two independent polls report: Poll A says 46% ± 4% support, Poll B says 51% ± 3% support (both at 95% confidence). What can you reasonably conclude?

Poll B proves support is above 50%

Poll A must be wrong because its margin of error is larger

The intervals overlap, so a real difference is not certain

The difference is statistically significant at 95%

Sample Question 3
A sample of 400 students finds that 30% prefer online classes. Approximate the 95% margin of error for this proportion using MOE ≈ 1/√n.

± 3.2%

± 5.0%

± 1.6%

± 10.0%

Jack is on a fitness campaign.He is measuring his improvement by counting the number of pushups he can do in one minute.He measures his progress at the end of each week.According to the line of linear regression, he has a Correlation Coefficient of 0.94.Which statement is most correct :

94% of the variation in his push up count can be explained by the number of weeks he has attended training

94% of the variation in his weekly attendance explained by the variation in his push-up count

89% of the variation in his push up count can be explained by the number of weeks he has attended training

89% of the variation in his weekly attendance explained by the variation in his push-up count

There relationship between attendance and pushups is non-linear
