To study the metabolism of insects, researchers fed cockroaches measured amounts of a sugar solution. After 2, 5, and 10 hours, they dissected some of the cockroaches and measured the amount of sugar in various tissues. 5 roaches fed the sugar D-glucose and dissected after 10 hours had the following amounts (in micrograms) of D-glucose in their hindguts:
55.95, 68.24, 52.73, 21.50, 23.78.
Consider these insects a random sample from the population of cockroaches and conduct a test to determine if the average level of D-glucose after 10 hours is less than 48 micrograms.
A) State the null and alternative hypothesis.
B) Calculate the test statistic. Show all work.
C) Find the p-value. Show work.
D) State the full conclusion, including an interpretation of what the evidence suggests.
Solutions
Expert Solution
So, we can conclude that the average level of D-glucose after 10 hours is significantly less than 48 micro grams.

To study the effect the ecological impact of malaria,
researchers in California measured the effect of malaria on what
distance an animal could run in 2 minutes. They used a sample of a
local lizard species, Sceloporis occidentalis, collected in the
field. They selected 15 lizards from those found to be infected
with the malarial parasite Plasmodium mexicanum and 15 lizards
found not infected. The distance each lizard could run in a time
limit of 2 minutes was recorded in...

In a study on the physical activity of people, researchers
measured overall physical activity as the total number of
registered movements (counts) over a period of time and then
computed the number of counts per minute (cpm) for each subject.
The study revealed that the overall physical activity of obese
people has a mean of μ=322cpm and a standard deviation σ=92cpm. In
a random sample of 100 obese people, consider x ̅, the sample mean
counts per minute.
Now suppose...

In a study examining 131 collared flycatcher eggs, researchers
measured various characteristics in order to study their
relationship to egg size (assayed as egg volume, in mm3 ). These
characteristics included nestling sex and survival. A single pair
of collared flycatchers generally lay around 6 eggs per breeding
season; laying order of the eggs was also recorded.
1. Is there evidence at the α = 0.10 significance level to
suggest that egg size differs between male and female chicks? If...

1. (5pt) In order to study the relation of weight to blood sugar
level, medical researchers considered a random sample of 12
patients. The observed Pearson correlation between weight and blood
sugar level was 0.63. Perform a hypothesis test for the presence of
correlation in the population at significance level 0.05.
2. (5pt) The researchers in the previous problem fit a simple
linear regression model to the same data with blood sugar level as
the response (Y) and weight as...
