A researcher studying frogs is investigating the distance that a certain species of frog can jump. The jump lengths appear to be approximately normally distributed with a mean of 85 inches and a standard deviation of 10 inches. Directions: Make a sketch of the "empirical rule" for this setting. a) What proportion of frog jumps are less than 75 inches? b) What jump lengths represent the middle 95% of frog jumps? Between and c) What is the probability of observing a random frog jump that is longer than 105 inches?

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 62 ounces and a standard deviation of 3 ounces.

Use the Standard Deviation Rule, also known as the Empirical Rule.

Suggestion: sketch the distribution in order to answer these questions.

a) 95% of the widget weights lie between blank and blank

b) What percentage of the widget weights lie between 59 and 68 ounces?

c) What percentage of the widget weights lie above 53 ?

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 63 ounces and a standard deviation of 7 ounces. Use the Standard Deviation Rule, also known as the Empirical Rule. Suggestion: sketch the distribution in order to answer these questions. a) 95% of the widget weights lie between and b) What percentage of the widget weights lie between 42 and 77 ounces? % c) What percentage of the widget weights lie below 70 ? %

The weight of an organ in adult males has a​ bell-shaped distribution with a mean of 310 grams and a standard deviation of 45 grams. Use the empirical rule to determine the following. ​

(a) About 68​% of organs will be between what​ weights? ​

(b) What percentage of organs weighs between 220 grams and 400 ​grams? ​

(c) What percentage of organs weighs less than 220 grams or more than 400 ​grams?

​(d) What percentage of organs weighs between 220 grams and 355 ​grams?

A sample of biological culture was submitted to a chemical laboratory for analysis of the percentage by weight of each major element. The composition of the cells by weight was found to be 48.9% C, 5.2% H, 24.8% O, 9.46% N, and 9.2% ash.

1. Prepare an empirical formula for the cells

2. Determine the COD/organic weight ratio for the cell

3. Determine the theoretical oxygen demand including both COD and NOD

   (nitrification oxygen demand)

4. If the organics are 80% biodegradable, what is the ultimate BOD of the sample?

5. What is the TOC?

Current activity in the hospital industry shows that hospitals are consolidating to form multihospital systems. Based on your reading in the text, what do empirical studies indicate concerning cost savings of multihospital systems over single hospital systems?

Why are multihospital systems expected to be cost saving?

Why would we continue to see multihospital systems forming even if cost savings are not as evident as expected?

A 38.40 mg sample of an organic acid composed of just carbon, hydrogen, and oxygen was burned in pure oxygen to give 37.54 mg CO2 and 7.684 mg H2O in a combustion analysis. In a separate experiment, the molecular mass was determined to be 90. In a titration, 40.2 mg of the acid dissolved in 50 mL of water required 14.28 mL of 0.0625 M NaOH for complete neutralization. Use these data to draw a reasonable Lewis structure for the compound.

Determine the empirical formula of the compound using the combustion analysis data.

The weight of an organ in adult males has a​ bell-shaped distribution with a mean of 310 grams and a standard deviation of 20 grams. Use the empirical rule to determine the following.

​(a) About 95​% of organs will be between what​ weights?

​(b) What percentage of organs weighs between 250 grams and 370 grams?

​(c) What percentage of organs weighs less than 250 grams or more than 370 ​grams?

​(d) What percentage of organs weighs between 250 grams and 330 grams?

Media Violence and the Cathartic Effect by Maria Florea (4p)

Which of the theories explored in the article do you feel best explains the relationship between the cathartic effect and media violence? Be sure to support your logic with empirical findings. Based on this logic do you feel that the cathartic effect can be applied to other areas of deviance outside of aggressive manifestations?

I want an answer please for this Q

1) Examine the nature, components and uses of theory in international relations as well as why theories can help us to understand the world. Be sure to also distinguish between empirical and normative theory in your answer AND to identify links between theory and practice.

2) Compare and contrast the main characteristics and assumptions of liberalism (idealism) and realism. Which one is more persuasive in its analysis of individuals, states and the international system in general and why? Be sure to use some examples in your answer.
