The heart rate of a healthy lion is approximately normally distributed with mean µ = 40...

The heart rate of a healthy lion is approximately normally distributed with mean µ = 40 beats per minutes. A heart rate that is too slow or too fast can indicate a health problem. A veterinarian has removed an abscessed tooth from a young healthy zoo lion. As the animal slowly starts to come out of the anesthetic, the heart rate is taken and recorded for half an hour (beats per minute): 30 37 43 38 35 36 Test the claim that the population average heart rate of the lion is different (either way) from 40 beats per minutes.

(a) State the null hypothesis and alternative hypothesis

(b)Find the test statistic

(c) If the type-I error α = 0.1, find the critical value(s) and shade the rejection region(s)

(d) Base on the type-I error α and rejection region(s), given above, what is your conclusion?

(e) Find the p-value

The cholesterol levels of women aged 21-40 in Canada are approximately Normally distributed with a mean of 190 miligrams per decilitre (mg/dl). In July of 2007, a clinical assessment applied in Toronto to random sample of twenty–nine Asian female immigrants aged 21-40 had a mean level of 179.52 mg/dl and a standard deviation of 38 mg/dl. (a) At the 10% level of significance test whether the mean cholesterol level of Asian women is the same as the national average. (b)...

1a) Suppose that memory for unrelated words is distributed normally with a mean of µ = 60 with a standard deviation of σ = 20. A random sample is selected from this population. After a treatment is administered to the individuals in the sample, a memory test that measures memory for unrelated words is administered, the sample mean is found to be M = 55. If the sample consists of n = 25 scores, can we conclude that the treatment...
