Determine the following for this data set:

1. the mean of the mean fecal testosterone levels reported above.

The mean of the fecal testosterone is 29.06/19=1.549

2. the truncated mean of the mean fecal testosterone levels reported above if your remove Goldilox's value from the data set.

After eliminating Goldilox's value the mean is 28.03/18= 1.557

3. the mode of the mean fecal testosterone levels reported above.

Mode of the values is 1.72

4. the midrange of the mean fecal testosterone levels reported above.

Midrange is 1.88+1.03=2.91/2=1.455

5. the median of the mean fecal testosterone levels reported above.

Median is 1.52

Part B

The following passage is from an article in the Journal of the American Medical Association. It contains two statistical arguments. For each one,

(b) the target, 8,724 individuals for 1 year

(c) the N, and 10.9 percent in emergencies and 13.6 percent in the control

(e) Evaluate this argument using the true premises and good form tests.
