Researchers are interested in whether long distance swimmers' heart rate differs from long distance runner's. They select 8 long-distance swimmers randomly, and calculate their heart rate as shown in table 3.
TABLE 3
| HEART RATE (BEATS PER MINUTE) | 46 | 52 | 64 | 55 | 48 | 59 | 58 |
66 |
The average heart rate of long distance runner in the general population is 60 beats per minute. Test the null hypothesis at the α=0.05 level of significance.

Researchers from the university of Kent, UK, were interested in
whether collectivist or individualist attitudes are related to
one’s intent to comply with social distancing and safety guidelines
during COVID-19. Participants were classified as either
collectivist or individualist, and rated their intent to comply
with guidelines on a scale from 1-5, where 1 is definitely not and
5 is definitely yes. Please conduct an independent-groups t test to
determine if there is a significant difference in intention to
comply between...

a) A researcher is
interested in determining if the IQ’s of prison inmates differs
from the that the general population, which has been shown to have
a mean IQ of 100 and a standard deviation of 15. The researcher
recruits a random sample of 25 inmates and finds that the average
IQ is 105.3 points. Test the null hypothesis at the .05 level. Show
all work and present a step by step hypothesis test summary as
shown in the text....

Finally, the researchers are interested in whether workplace
cohesion attitudes change, as employees move from sub-optimal
working conditions to above average working conditions. They
collect data from the same employees, first when working under
sub-optimal conditions and then one month after moving to above
average conditions. Test for this hypothesis based on the new data
below.

A medical researcher is interested in whether calcium intake
differs, on average, among elderly individuals with normal bone
density, with osteopenia (a low bone density that may lead to
osteoporosis), and with osteoporosis. He recruits consenting 60
individuals over the age of 65 using his patient records from his
hospital (20 from each of the three bone density groups). You may
assume that the individuals in each group constitute a simple
random sample from consenting patients from that hospital. The...

Researchers are interested in whether there is a difference in
happiness levels between people that live on the West Coast and
people that live on the East Coast. A simple random sample of
people were selected from each coast to take an assessment of their
happiness. Scores on the happiness assessment range from 1-20.
The happiness scores for the individuals assessed are below.
East Coast Happiness Scores
West Coast Happiness Scores

Researchers are interested in the effect of a certain nutrient
on the growth rate of plant seedlings. Using a hyproponics growth
procedure that used water containing the nutrient, they planted six
tomato plants and recorded the heights of each plant 14 days after
gemination. Those heights, measured in millimeters, were as follows
: 55.5, 60.3, 60.6, 62.1, 65.5, 69.2. Test the claim that the mean
tomato plants’heights is different than 65 millimeters. Assume the
random sample assumption holds. Use α...
