Question

Sports psychologists are interested in whether the pulses of long-distance runners differ from those of other athletes. They obtain a random sample (N = 8) of long-distance runners, measure their resting pulses, and obtain the following data:

45, 42, 64, 54, 58, 49, 47, and 55 (beats per minute)

The average resting pulse of athletes in the general population is 60 beats per minute.

            Conduct a statistical test based on the .05 significance level (i.e., ? = .05) to conclude whether or not the pulses of long-distance runners differ from those of other athletes.

Hypothesis set up

Population 1:                                                                                                    (µ1 =               , ?1 =               )
Note the subscription can vary depending on the research scenario. Also, unknown could be an answer.

Sample of population 1: ________________________________________ ( = ________, s =________)

Population 2:                                                                                                   (µ2 =               , ?2 =               )

Null hypothesis (verbal description followed by symbols representing the hypothesis):

_______________________________________________________________________________ (H0:           ).

Alternative hypothesis (verbal description followed by symbols representing the hypothesis): _______________________________________________________________________________ (Ha:           ).

This is a (directional / nondirectional) hypothesis (one / two -tailed hypothesis).
