People who experience online harassment either ignore it
or respond via postings or involving authorities. Is one
method more effective than the other? A 2014 Pew

American adults, found that 412 of the 549 respondents
who had chosen to ignore online harassment thought that it

How large is the difference? Obtain and interpret in context
a 95% confidence interval for the difference between the
proportions of American adults who find ignoring online
harassment effective and those who find responding to
it effective.
Provide the lower and upper bounds of the 95% confidence
interval. Give your answers to three decimal places.
Lower bound =
Upper bound=
0.133
