Test-based confidence intervals

Pointed out by David Naeger:– From help epitab:– tb requests that test-based confidence intervals

be calculated wherever appropriate in place of confidence intervals based on other approximations or exact confidence intervals.

So tb makes the confidence intervals and the P-values agree, but it is by making the CI wrong.

FAA spokesman Greg Martin said requiring the seats would harm more children than it would protect.

"A lap child held firmly by a parent doesn't result in second- or third-degree burns like an unsecured pot of coffee," Martin said.

Three children who sat in their parents' laps were among the 309 who survived the fiery crash of an Air France Airbus A340 after it overshot the Toronto runway, Martin noted.
