A team of researchers wanted to assess the effectiveness of the 4 components of a weight loss program by comparing the distribution of weight status across 4 different treatment groups. The data is summarized in the table below:
|
Weight Status |

|
Intervention Component |
Normal Weight |
Overweight |
Obese |
|
Control Group (n=100) |

Physical Activity (n=100) |
73 |

12 |
|
Combination (n=100) |

Is there a difference in weight status by intervention component? (Hint: Are intervention component and weight status independent?) Run the appropriate test at a 5% level of significance.
- Compute the expected (E) number of students for each category: (7.5pts)

Researchers wanted to compare the effectiveness of a water
softener used with a filtering process with a water softener used
without filtering. Ninety locations were randomly divided into two
groups of equal size. Group A locations used a water softener and
the filtering process, while group B used only the water softener.
At the end of three months, a water sample was tested at each
location for its level of softness. (Water softness was measured on
a scale of 1...

learning outcomes of courses that are offered in traditional
face-to-face classroom as compare with online sections. section 1
(traditional classroom) consisted 101 students and section 2
(online class) were 105 students. At the end of the semester the
researchers measured achievement scores. students in section 1 had
an average of 85 with standard deviation of 6.5 and section 2

A team of researchers has developed a new weight loss
supplement. They want to know if patients who use the new
supplement for four weeks lose any weight. The supplement has some
minor side effects including mild headaches and achiness. If the
researchers obtain evidence of weight loss they will proceed to
produce the supplement commercially and sell it for a large profit.
If they do not obtain evidence of weight loss, the project will be
ended.

People gain weight when they take in more energy from food than
they expend. Researchers wanted to investigate the link between
obesity and energy spent on daily activity. Choose 20 healthy
volunteers who don't exercise. Deliberately choose 10 who are lean
and 10 who are mildly obese but still healthy. Attach sensors that
monitor the subjects' every move for 10 days. The table below
presents data on the time (in minutes per day) that the subjects
spent standing or walking,...
