6.2 Confidence Interval Check
for Understanding
Two footballs, one filled with air
and the other filled with helium,
were kicked on a windless day at
Ohio State University. The
footballs were alternated with
each kick. After 10 practice kicks,
each football was kicked 29 more
times. Assume the distances are
normally distributed for each
football. The distances (in yards)
are here in StatCrunch.
Which distribution (z or t) should
you use to construct a
confidence interval and why?
Construct a 95% confidence
interval for the population mean
distance travelled for each
football.
Interpret your confidence
intervals.
Draw both of your intervals here
with the same x-axis. You can
draw them by hand or with
technology. What do you
notice? What conclusions might
you draw from this illustration?
