The file P07_14.xlsx contains a very small population of only
five members. For each member, the height of the person is listed.
The purpose of this problem is to let you see exactly what a
sampling distribution is. Find the exact sampling
distribution of the sample mean with sample size 3. (If necessary,
round your answers to four decimal places.) Prefer to be shown

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,

Can it be concluded, from this data, that there is a significant
difference between the two population means?
Let d=(Population 1 entry)−(Population 2 entry) . Use a
significance level of α=0.01 for the test. Assume that both
populations are normally distributed.
Step 1 of 5:
State the null and alternative hypotheses...

Suppose the height of individuals in a population follow a
normal distribution with a mean (μ) of 66 inches and a standard
deviation (σ) of 4 inches.
a) Using the statistical software R, sample n individuals from
the distribution described above. For N=10,000 iterations, compute
the average height for n=5, n=15, n=50, n=100 individuals and plot
a histogram of the sampling distribution of the Z score (?̅−??/√?
)
b) Using the statistical software R, sample n individuals from
the distribution...
