In a statistics class, 8 students took their pulses before and after being frightened. The frightening event was having the teacher scream and run from one side of the room to the other. The pulse rates (beats per minute) of the students before and after the scream were obtained separately and are shown in the table. Treat this as though it were a random sample of community college students. Test the hypothesis that the mean of college students' pulse rates is higher after a fright using a significance level of 0.05. Do the 5-step hypothesis test and submit an image of each step. show your work.
| Participant # | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

A study monitored responses to stressor. After being exposed to
a stressor, the hearth rates of the subjects were recorded.The
sample of 21 persons had are x=75 beats per second and s=6.83 beats
per second. The normal pulse of a person is 73 beats per second.
Test the hypothesis that there is no significant difference between
a normal heart rate and that of a stressed pet owner (use α=.05).

HI6007 Statistics for Business Decisions
Tutorial 7 – Week 8
Question 1:
The average starting salary of students who graduated from
colleges of Business in 2009 was $48,400. A sample of 100 graduates
of 2010 showed an average starting salary of $50,000. Assume the
standard deviation of the population is known to be $8000. We want
to determine whether or not there has been a significant increase
in the starting salaries.

Please note that for all problems in this course, the
standard cut-off (alpha) for a test of significance will be .05,
and you always report the exact power unless SPSS output states
p=.000 (you’d report p<.001). Also, remember when
hand-calculating, always use TWO decimal places so that deductions
in grading won’t be due to rounding differences.

perception skills of 32 deaf children: 16 subjects with at least
one cochlear implant (CI) and 16 subjects (with hearing loss)
without an implant. (CI subjects were implanted at 13 or 14 months
of age. So, no subjects had CIs at the time of the first data
