Write each statement:

    • null hypothesis):
    • alternative hypothesis):
  • Write the “test statistic” here:
  • Write the P-value here:

  • REJECT YES or NO
  • What is your conclusion?
  • What is your conclusion? Is there a difference between the average score for each decade?

Construct a 95% confidence interval estimate. Does this interval contain zero? Do the results of this problem support the results of the previous?

What is the Confidence Interval Estimate:

  • Does the interval indicate a difference or not? Explain your answer.

Do the results of the hypothesis test and the confidence interval estimate support each other?

At the Olympic-level of competition, even the smallest factors can make the difference between winning and losing. For example, Pelton (1983) has shown that Olympic markspersons shoot much better if they fire between heartbeats, rather than squeezing the trigger during a heartbeat. The small vibration caused by a heartbeat seems to be sufficient to affect aim. A sample of n=12 Olympic markspersons fires a series of rounds while a researcher records heartbeats. For each marksperson, a scores is recorded for...
