• a only

• b only

• c only

• a and b only

• b and c only

• x +/- s

• x +/- sigma

• x +/- (standard deviation of x)

• x +/- k(standard deviation of x)

• either a or b, depending on whether sigma is known

• The second interval would have the same width as the original interval

• The second interval would be wider than the original interval

• The second interval would be narrower than the original interval

• The width of the second interval would either be the same or wider, but it is not possible to tell which

• It is not possible to tell how the second interval width would compare to the original interval, because both the sample size and the confidence interval are changed

• The width of the interval will be unchanged

• The interval will become wider

• The interval will become narrower

• The interval width will not stay the same, but we can't tell whether the interval will become narrower or wider

• It is not possible to tell based on the information given
