Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
Options are
A. Their confidence interval would be less likely to capture the sample mean.
B. The probability of selecting a sample which doesn't capture the true value of μ would be 10% rather than 5% if they decide to calculate a 90% confidence interval rather than a 95% confidence interval from the sample they will select.
C. They would increase the margin of error of their confidence interval if they calculated a 90% rather than a 95% confidence interval.
D. They would decrease the margin of error of their confidence interval if they calculated a 90% rather than a 95% confidence interval.
A. Confidence interval is pivoted around mean. So this is an incorrect option.
B. 90% sample values around mean will be included in case of 90% confidence interval and 95% sample values around mean wil be included in case of 95% confidence interval. So this option is correct
C. Margin of error increases with increase in confidence interval as likelihood of a sample value deviating from mean increases. So this is incorrect.
D. same explanation as above
