Question

a. In constructing 90% confidence intervals for means what do we expect ill be true over the long run? select ali that apply you have attempts O 90% of the time, the population mean will fall outside the confidence interval. O 90% of the time, the population mean will fall inside the confidence interval. O 10% of the time, the population mean will fall outside the confidence interval. O 10% of the time, the population mean will fall inside the confidence interval b. In constructing 98% confidence intervals for means, what do we expect will be true over the long run? select all that app y you have three attempts. (Hint: Drawing a diagram of a confidence interval and considering scenarios in which the population mean is inside or outside the interval might help.) O 98% of the time, the difference between the sample mean and population mean will be less than the margin of error. O 98% of the time, the sample mean and the population mean will be exactly equal to each other O 2% of the time, the difference between the sample mean and population mean will be less than the margin of error. O 2% of the time, the difference between the sample mean and population mean wil be greater than the margin of error 98% of the time, the difference between the sample mean and population mean will be more than the margin of error

Explanation / Answer

a) 90% confidence interval means the population mean will fall 90% inside the interval and 10% times outside the interval. Hence,

Option B and Option C are correct.

b) Similar logic as problem a), inside the interval means difference less than margin of error. Hence:

Option A and Option D are correct.
