The Heights (In Cm)for a Random Sample of 60 Males

question 53

Multiple Choice

The heights (in cm) for a random sample of 60 males were measured.The sample mean is 166.55,the standard deviation is 12.57,the sample kurtosis is 0.12,and the sample skewness is −0.23.The following table shows the heights subdivided into non-overlapping intervals. For the goodness-of-fit test for normality,the null and alternative hypothesis are ______________________________________________________________________.

• A) H₀: Heights follow a normal distribution with mean 166.55 and standard deviation 12.46,H_A: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.46
• B) H₀: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.46,H_A: Heights follow a normal distribution with mean 166.55 and standard deviation 12.46
• C) H₀: Heights follow a normal distribution with mean 166.55 and standard deviation 12.57,H_A: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.57
• D) H₀: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.57,H_A: Heights follow a normal distribution with mean 166.55 and standard deviation 12.57

Explain the concept of countercurrent exchange and its role in maximizing oxygen absorption in aquatic organisms.

Identify the primary sites of gas exchange in different groups of animals, including mammals, birds, insects, and aquatic organisms.

Describe the process of gas exchange at the cellular level, including oxygen and carbon dioxide transport.

Understand the factors affecting gas exchange efficiency, such as surface area, concentration gradients, and medium properties (water vs. air).
