Answer:
Step-by-step explanation:
Confidence interval is one which has centre as mean. The width of the interval would be 2 times margin of error.
Margin of error = Critical value * Std error/sq rt of sample
Hence if margin of error is lower for same n, then it means lower confidence level. Option a is right
Similarly, if bigger the sample size, lower is margin of error . Hence option b is right
c) False. Smaller samples make margin of error big and hence confidence intervals bigger.
d) If n becomes 9n, then margin of error becomes 1/3 Hence option d is right.
