## Weatherwise is a magazine published by the American Meteorological Society.

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of μ = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers.

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.

In a random sample of 62 professional actors, it was found that 36 were extroverts.

(a) Let p represent the proportion of all actors who are extroverts. Find a point estimate for p. (Round your answer to four decimal places.)

(b) Find a 95% confidence interval for p. (Round your answers to two decimal places.)

2) Consider the following two propositions:

p: It snows tonight.

q: I will stay home.

Use negation (~), conjunction (˄), disjunction (˅), and/or implication (→) to construct a logical equivalence of p→q.

Construct the truth table for both statements and explain how the truth tables establish logical equivalences.

## Imagine a country path, D, in miles in length, which a person walks

Imagine a country path, D, in miles in length, which a person walks at a steady pace in T hours. Suppose that a straight line represents the cartesian graph of time (T) versus the distance (D) for this walk. What is the slope of this straight line graph, and what does it represent?

Can you think of another example, which, if visually depicted, would have a straight line for its graph?

Minimum words - 200 words (at least). Good grammar and logic of presentation required.
