## Analysis of Test Scores by GenderIn a study involving a group of students, their grades and gender were collected and summarized in a table. The table below shows the distribution of grades (A, B, and C) among male and female students:| | A | B | C | Total ||--------|----|----|----|-------|| Male | 16 | 18 | 15 | 49 || Female | 2 | 4 | 17 | 23 || Total | 18 | 22 | 32 | 72 |### Objective:Let $ \pi $ represent the percentage of all male students who would receive a grade of B on this test. The goal is to use a 90% confidence interval to estimate $ \pi $ to three decimal places.### Task:Enter your answer as a tri-linear inequality using decimals (not percents).\[ \_\_\_\_ \leq \pi \leq \_\_\_\_ \]

Giving a test to a group of students, the grades and gender are summarized below A Total Male 16 18 15 49 Female 4 17 23 Total 18 22 32 72 Let T represent the percentage of all male students who would receive a grade of B on this test. Use a 90% confidence interval to estimate p to three decimal places. Enter your answer as a tri-linear inequality using decimals (not percents).

Joselyn hopes to receive a grade of B or better in her statistics class. Currently she has scored 75, 83, and 81 on her three in-class tests and also has a homework average of 88. Her professor calculates the class grade by finding the mean of five grades: three in-class tests, the homework average and the final exam. What is the minimum score Joselyn must earn on the final exam to have a class grade (mean) of 80? A. 67 B. 95 C. 70 D. 73

You saw back in Chapter 2 that the mean, median, mode, and midrange are used to indicate where data is centered in a data set, or in other words what a typical value in the set is. A question that is often asked is, "If they're all supposed to do the same thing, why is there more than one?" Isn't one enough? In this exercise, you will be given two small sets of data. For each set, a. find the mean, median, mode and midrange b. in your opinion, decide which of the measures BEST represents all the values in the set (best indicates a typical value), and which one does this the WORST. c. post your responses and justify them by explaining why Don't forget to respond to at least one of your classmate's posts. With this exercise, "more is better." I'll elaborate after the deadline. • Set A: the salaries of 10 employees at a company (in thousands of dollars): 50, 50, 50, 50, 50, 50, 50, 50, 50, 500 • Set B: the grades of 9 students on an exam: 20, 25, 30, 35, 40, 45, 100, 100, 100
Set your utility for $0 to be 0 and $1 million to be 100. Apply the simple decision tree used in determining your utility for money, where the lottery has a prize of $1 million if you win and $0 if you lose, to determine your utility for $500,000 and $200,000. Use these 4 utilities to draw your utility curve for money.

In this problem, we explore the effect on the mean, median, and mode of adding the same number to each data value. Consider the data set 4, 4, 5, 8, 12. (a) Compute the mode, median, and mean. (Enter your answers to one decimal place.) mode median mean (b) Add 3 to each of the data values. Compute the mode, median, and mean. (Enter your answers to one decimal place.) mode median mean

Use the table to answer the question. Has a Cell Phone Does Not Have a Cell Phone Totals Has a Computer 44 176 220 Does Not Have a Computer 26 104 130 Totals 70 280 350 The table above gives a summary of survey data asking respondents if they owned a computer or a cell phone. Is there an association between owning a computer and owning a cell phone? Explain, rounding your answer to the nearest whole percent as necessary. There is an association since the conditional relative frequencies of owning a cell phone are 20% for those who own computers and those who do not. There is not an association since the conditional relative frequencies of owning a cell phone are 20% for those who own computers and those who do not. There is not an association since the conditional relative frequency of owning a cell phone is 63% for those who own computers and 37% for those who do not.
