Question

data on the heights of 37 randomly selected female engineering
students at UH:

62 64 61 67 65 68 61 65 60 65 64 63 59

68 64 66 68 69 65 67 62 66 68 67 66 65

69 65 69 65 67 67 65 63 64 67 65

We found that the sample mean and sample standard deviation for
this sample data are 65.16 inches and 2.54 inches, respectively. Do
you find sufficient evidence in the sample data to support the
claim that the mean height of female engineering students at UH is
greater than 65 inches at α = 0.05? Answer this question using both
fixed-? approach and P-value approach. (Hint: for P-value approach,
you need to find P-value range using the t-table as demonstrated in
the lecture)

Answer #1

A randomly selected sample of college basketball players has the
following heights in inches.
63, 62, 71, 63, 63, 63, 69, 61, 68, 64, 62, 62, 65, 69, 69, 71,
66, 62, 63, 64, 66, 61, 63, 67, 65, 64, 63, 61, 68, 68, 67, 62
Compute a 95% confidence interval for the population mean height
of college basketball players based on this sample and fill in the
blanks appropriately.
______< μ <_____ (Keep 3 decimal places)

6 Use 10 bins with the first
centered on 61 in. and of width 1 in.
Construct a histogram for the female
student height data in Exercise 6.2.8.
The female students in an undergraduate engineering core course
at ASU self-reported their heights to the nearest inch. The data
follow. Construct a stem-and-leaf diagram for the height data and
comment on any important features that you notice. Calculate the
sample mean, the sample standard deviation, and the sample median
of height.

DaughtersHeight.sav is a data set on the height of
adult daughters and the heights of their mothers and fathers, all
in inches. The data were extracted from the US Department of Health
and Human Services, Third National Health and Nutrition Examination
Survey? Analyze these data with child height as the dependent
variable. What can you conclude? Can female daughter height be
related to the height of the father and/or the mother? Conduct a
separate analysis with Type I and Type III...
