Researchers are interested in the effect of a certain nutrient on
the growth rate of plant seedlings. Using a hydroponics grow
procedure that utilized water containing the nutrient, they planted
six tomato plants and recorded the heights of each plant 14 days
after germination. Those heights, measured in millimeters, were as
follows: 54.7 58.8 60.5 63.3 64.8 68.1 a. Find a point estimate of
the population mean height of this variety of seedling 14 days
after germination. b. Given a margin of error of 5.0 mm, construct
a 95% confidence interval for the population mean height. c. Use
this example to explain why a point estimate alone is usually
insufficient for statistical inference.

Researchers are interested in the effect of a certain nutrient
on the growth rate of plant seedlings. Using a hyproponics growth
procedure that used water containing the nutrient, they planted six
tomato plants and recorded the heights of each plant 14 days after
gemination. Those heights, measured in millimeters, were as follows
: 55.5, 60.3, 60.6, 62.1, 65.5, 69.2. Test the claim that the mean
tomato plants’heights is different than 65 millimeters. Assume the
random sample assumption holds. Use α...

Researchers are interested in the mean age of a certain
population. Let us say that they are asking the following
questions: can we conclude that the mean age of this population is
different from 30 years? If the sample mean of 10 individuals drawn
from that population is 27and the population variance is 20. Make a
confidence interval of the mean

2. Suppose that the researchers are interested in the effect of
class size on only female student test scores. They consider using
the following method to reconstruct their treatment and control
groups: select all female students who have been assigned to small
size classes as their new treatment group and select all female
students who have been assigned to normal size classes as their new
control group. Is this method problematic?

Researchers studying the effect of diet on growth would like to
know if a vegetarian diet affects the height of a child. Twelve
students are randomly selected that are all 6-years old. The
average height of these kids is 42.5 inches with a standard
deviation of 3.8 inches. The average height of all 6-year old kids
is found to be 45.75 inches. Conduct a hypothesis test to determine
if there is overwhelming evidence at alpha = .05 that 6-year old...
