What’s wrong with this?

1. During the fasting phase, the central nervous system is using glucose and amino acids for energy.

2. The chief substrate for gluconeogenesis during the fasting state is ketones.

3. Liver glycogen is highest during the starvation state.

4. Large amounts of ketones in the blood indicates metabolism of glucose.

5. The red blood cells need to always use glucose for energy because they do not contain a nucleus.

6. Red blood cells always make ATP via aerobic metabolism

7. Insulin levels are likely to be high during the postabsorptive phase.

8. The chief substrate for gluconeogenesis during the fasting state is glycerol from fat mobilization.

9. The largest loss of urinary nitrogen is associated with the post-absorption phase.

10. NADPH + H needed for fatty acid synthesis in the starvation phase.

11. The TCA cycle can best be described as catabolic.

12. Ketones are made from glucose.

13. During the starvation phase the primary substrate for gluconeogenesis is acetyl CoA.

14. The most gluconeogenic amino acid is leucine.

QUESTION 1 (60) Much debate exists within the literature about leadership and management. Kotter (1990:103) argues that management and leadership are “two distinctive and complementary systems of action” and that the former involves coping with complexity, while the latter involves coping with change.

1.1 Discuss in detail, with the use of examples, the fundamental differences between the concept of leadership versus management. (20)

1.2 Evaluate in detail, with the use of practical examples, the advantages and disadvantages of a transformational leader. (20)

1.3 Discuss in detail, with the use of practical examples, FOUR (4) management styles and the potential impact each style may have on a business. (20)

1.) Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past 8 weeks, a veterinarian took the following glucose readings from this horse (in mg/100 ml).

The sample mean is x ≈ 94.0. Let x be a random variable representing glucose readings taken from Gentle Ben. We may assume that x has a normal distribution, and we know from past experience that σ = 12.5. The mean glucose level for horses should be μ = 85 mg/100 ml.† Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use α = 0.05.

2.) Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna).† Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows.

The sample mean is x = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and σ = 0.66 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is μ = 4.40 grams.

3.) The price to earnings ratio (P/E) is an important tool in financial work. A random sample of 14 large U.S. banks (J. P. Morgan, Bank of America, and others) gave the following P/E ratios.†

The sample mean is

x ≈ 17.1.

Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of a certain stock index is μ = 18. Let x be a random variable representing the P/E ratio of all large U.S. bank stocks. We assume that x has a normal distribution and σ = 4.7. Do these data indicate that the P/E ratio of all U.S. bank stocks is less than 18? Use α = 0.05.

4.) Nationally, about 11% of the total U.S. wheat crop is destroyed each year by hail.† An insurance company is studying wheat hail damage claims in a county in Colorado. A random sample of 16 claims in the county reported the percentage of their wheat lost to hail.

The sample mean is x = 12.6%. Let x be a random variable that represents the percentage of wheat crop in that county lost to hail. Assume that x has a normal distribution and σ = 5.0%. Do these data indicate that the percentage of wheat crop lost to hail in that county is different (either way) from the national mean of 11%? Use α = 0.01.

5.) Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about μ = 28 ml/kg.† Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows.

The sample mean is x ≈ 33.1 ml/kg. Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and σ = 4.75. Do the data indicate that Roger's red blood cell volume is different (either way) from μ = 28 ml/kg? Use a 0.01 level of significance.
