Question

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).

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.

problem.
According to the Center for Disease Control (2016), the mean
height of adults ages 20 and older is about 66.5 inches (69.3
inches for males, 63.8 inches for females). We will test if the
mean height of our sample data (n = 30) is significantly different
than 66.5 inches (our test statistic) using a one-sample t-test.
Conduct a two-tailed, one-sample t-test with alpha set at .05.

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...
