QUESTION 11 You are the head of fundraising for the Fayetteville Boys and Girls Club. You believe that nationally, over the past year, people have reduced the average amount that they donate when making one-time gifts to nonprofits such as the Boys and Girls Club. Results from a national survey of nonprofits indicate that last time gift donation was $85. To test your belief, you conducted a new survey on 64 nonprofit organizations and you found that this year, the mean one-time gift donation the mean one was $82 with a standard deviation of $9. What is the correct conclusion with a 0.10 level of significance? Oa. Fall to reject He conclude that the mean one-time gift donation has decreased from $85. Ob. Reject Ho conclude that the mean one-time gift donation has decreased from $85 Oc. Reject Ho there is not enough evidence to conclude that the mean one-time gift donation has decrease 5 Od. Fail to reject there is not enough evidence to conclude that the mean one-time gift donation has decreased from $85.

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

A friend of yours tells you that they heard that 65% of all college athletes end up losing a finger or toe in their college athletic career.  You're highly skeptical of this, but your not sure if that percentage is an over exageration or an under exageration.  You survey 101 former student-athletes and find that 60 of them lost a digit during their college athletic career.  Is this enough evidence to conclude that the true percentage of student-athletes that lose a digit during their collegiate career is really different from 65%?

Determine if the following is an example of descriptive or inferential statistics. 85 randomly selected fifty-year-old Americans were asked how much money they had saved for their retirement. The average for these respondents was $25,000, the minimum was $0 and the maximum was $1,200,000. Descriptive Statistics Inferential Statistics

find an example of when statistics were misused/skewed and state the reason why you think the statistics were reported that way.

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.”   Identify the reason for mean incomes for households being higher than median incomes for households.

Of the 328 patients that completed the survey last year, 211 of them claimed to be returning patients which is 64.3% of the sample. What type of data, quantitative or categorical, is the question “How long did you wait past your appointment time?” asking for? Justify your answer.

A story describing a burger taste test among non-vegetarians was read by 352 high school students. To investigate the effect of the type of burger (veggie or meat) on subject's opinion of whether or not the burger tasted good, each burger had labels of veggie burger, beef burger, or a burger with no label. Each person was asked whether the burger tasted was good or not. Data are given in the accompanying table. Is there evidence that the proportion who believe that the burger tasted good for the three different labels differ? Test the relevant hypotheses using ? = 0.01. (Round your answer to two decimal places.)
