ZPharma Co., a pharmaceutical company, sells three different products: Zdiet, a Weight Loss Medication, Zataflam, a Non-Steroidal Anti-Inflammatory and Zolymox, an Antibiotic. Due to a new government regulation with regard to pricing medications, suppose that the prices of these products have increased as follows: Zdiet (25%), Zataflam, (20%) and Zolymox, (10%). As a result, the monthly quantity sold from each product declined by the following percentages: Zdiet (35%), Zataflam (12%), and Zolymox (5%). Calculate the price elasticity of demand for the three products: Zdiet, Zataflam and Zolymox. Interpret your results to the best of your ability. Analyze the potential effect of the increase in prices on sales revenue of each product. Now, suppose the decline in demand indicated above was caused by a 20% decrease in income level. How would you best describe each product

Students in a biology class have been randomly assigned to one of the two mentors for the laboratory portion of the class. A random sample of final examination scores has been selected from students supervised by each mentor, with the following results:
Mentor A: 78, 78, 71, 89, 80, 93, 73, 76
Mentor B: 74, 81, 65, 73, 80, 63, 71, 64, 50, 80
At the 0.05 significance level, is there a difference in the mean scores?

Q1. Discuss the tools to measure central tendency?

Q2. I need new and unique answers, please.

a) Discuss parametric and nonparametric test used for    hypothesis testing.

b) In a cross sectional study on coronary heart disease (CHD), the smoking and CHD status is summarized below. Use appropriate statistical test to conclude smoking plays any role in CHD.

A national health survey found that men’s heights are normally distributed with mean 69.0 and a standard deviation of 2.8 inches. The same survey found that woman’s heights are normally distributed with a mean of 63.6 and a standard deviation of 2.5 inches. (a) If the International Tall club has a minimum height requirement of 74 inches, what percentage of men meet this requirement? (b) If the International Tall Club accepts the tallest 4% of all women, what is the new minimum height for women?

The height (in inches) of a random sample of 8 National Basketball Association players is shown below.

Please find the Lower AND Upper bound of the above number set:

36, 52, 60, 60, 62, 65, 65, 65, 70, 72, 74, 75, 75, 76, 76, 78, 79, 79, 80, 80, 82, 83, 84, 85, 88, 90, 90, 92, 95, 98, 99

(NOTE: The answer is not 36 nor 42 for low bound nor 81.37 nor 110 for the upper bound. These were incorrect answers.)

A random sample of size n₁ = 14 is selected from a normal population with a mean of 74 and a standard deviation of 6. A second random sample of size n₂ = 9 is taken from another normal population with mean 70 and standard deviation 14. Let X¯1and X¯2 be the two sample means. Find:

(a) The probability that X¯1-X¯2 exceeds 3.

(b) The probability that 4.4 ≤X¯1-X¯2≤ 5.4.

Measuring Economic Exposure. Assume you live in the U.S. Using the following cost and revenue information shown for DeKalb, Inc.,

a) determine how the costs, revenue, and net cash flow would be affected by three possible exchange rate scenarios for the New Zealand dollar (NZ$):

            1) NZ$ = $0.55,

            2) NZ$ = $0.60, and

            3) NZ$ = $0.65.

            b) What is your conclusion?
