A university health center tracks the number of flu-related visits during each month of the fall semester. The center director wonders whether students come down with the flu more often around mid-October)and mid December. Can these data shed any light on this issue?

Flu-Related Visits to the University Health Center

(by months)

      Is there any significant difference among the flu-related visits during the fall semester? Use an α level of .05 to test the appropriate hypothesis,

Suppose we know that at a University XYZ that 15% of students receive an A in their introductory statistics class, 20% receive a B, 30% receive a C, 10% receive a D, and the rest receive an F. For comparison, a sample of 260 students at University ABC is taken and 20% received an A, 25% received a B, 25% received a C, 10% received a D, and the remaining students failed the class. When testing (at the 5% level of significance) whether the proportions between the two universities are different, what is the critical value? (please round your answer to 3 decimal places)

Brief Introduction

Suppose that you are an analyst for the ABC Company, a large consulting firm with offices around the world. The company wants to build a new knowledge management system that can identify and track the expertise of individual consultants anywhere in the world on the basis of their education and the various consulting projects on which they have worked. Assume that this is a new idea that has never before been attempted in ABC or elsewhere. ABC has an international network, but the offices in each country may use somewhat different hardware and software. ABC management wants the system up and running within a year.

Find an example of an industry that has undergone a technological paradigm shift in recent years. What happened to the established companies as that paradigm shift unfolded? This module requires you to analyze the industry environment in which your company is based and determine if it is vulnerable to a technological paradigm shift. With the information you have at your disposal answer the following questions: What is the dominant product technology used in the industry in which your company us based? Are technical standards important in your industry? If so what are they? What are the attributes of the majority if customers purchasing the product of your company? What does this tell you about the strategic issues that the company is likely to face in the future? Did the dominant technology in your industry diffuse Rapidly or slowly? What drove the speed of diffusion?

A group of 43 college students from a certain liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The purpose of this study was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.

The group of 43 students in the study reported an average of 5.52 drinks per with a standard deviation of 3.64 drinks.

Find the p-value for the hypothesis test.

The p-value should be rounded to 4-decimal places.

Commute times in the U.S. are heavily skewed to the right. We select a random sample of 220 people from the 2000 U.S. Census who reported a non-zero commute time.

In this sample the mean commute time is 28.3 minutes with a standard deviation of 19.2 minutes. Can we conclude from this data that the mean commute time in the U.S. is less than half an hour? Conduct a hypothesis test at the 5% level of significance.

What is the p-value for this hypothesis test?

Your answer should be rounded to 4 decimal places.

Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her university to see if there is evidence to show that this is not true at her university. A random sample of 33 students were asked to keep a diary of their activities over a period of several weeks. It was found that the average number of hours that the 33 students studied each week was 22.2 hours. The sample standard deviation of 3.9 hours.

Find the p-value.

The p-value should be rounded to 4-decimal places.

A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study have their blood pressure taken at the beginning of the study. After being on the medication for 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test.

Change: Final Blood Pressure - Initial Blood Pressure

The researcher wants to know if there is evidence that the drug affects blood pressure. At the end of 4 weeks, 33 subjects in the study had an average change in blood pressure of -2.9 with a standard deviation of 5.4.

Child Health and Development Studies (CHDS) has been collecting data about expectant mothers in Oakland, CA since 1959. One of the measurements taken by CHDS is the weight increase (in pounds) for expectant mothers in the second trimester.

In a fictitious study, suppose that CHDS finds the average weight increase in the second trimester is 14 pounds. Suppose also that, in 2015, a random sample of 37 expectant mothers have mean weight increase of 16.2 pounds in the second trimester, with a standard deviation of 5.6 pounds.

A hypothesis test is done to see if there is evidence that weight increase in the second trimester is greater than 14 pounds.

Find the p-value for the hypothesis test.

The p-value should be rounded to 4 decimal places.
