The mean IQ for the U.S. is 100 with a standard deviation of 15. A Troy statistics professor thinks Troystudents are smarter than average, so he randomly samples 10 students and records the following IQ data totest his hypothesis. How would you describe the data in terms of skewness:IQ: 95 100 105 110 115 100 105 110 105 105O positively skewedO negatively skewedOsymmetrical-no skewnessO inversely skewedO conversely skewed The mean IQ for the U.S. is 100 with a standard deviation of 15. A Troy statistics professor thinks Troystudents are smarter than average, so he randomly samples 10 students and records the following IQ data totest his hypothesis. What conclusion should you make?IQ: 95 100 105 110 115 100 105 110 105 105O the data support the claim that Troy students have an IQ greater than 100O the data do not support the claim that Troy students have an IQ greater than 100the data support the null hypothesisO the data fail to support the alternative hypothesis

Which of the following is an example of doing inferential statistics? You calculate the average grade on an exam in a class of 5th grade math students to see if they did better or worse than last year. You lookup the median and the standard deviation of the age for the U.S. population from U.S. Census data. You use a sample of homes in Rancho Cucamonga to draw a conclusion about the mean home price for all Rancho Cucamonga homes. You compare the distributions of scores for two Social Science 10 classes to see which class did better on the exam.
The college physical education department offered an advanced first aid course last summer. The scores on the comprehensive final exam were normally distributed, and the z-scores for some of the students are shown below. Robert 1.24 Juan 1.66 Haley −1.84 Joel 0.00 Jan −0.84 Linda 1.68 Which of these students scored above the mean? (Select all that apply.) Which of these students scored on the mean? (Select all that apply.) Which of these students scored below the mean? (Select all that apply.) If the mean score was μ = 140 with standard deviation σ = 15, what was the final exam score for each student?

(a) TV stations use ratings to decide which shows to keep or cancel. Therefore, the A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ: 1. Identify the variable. 2. Identify the two populations. 3. Identify the pairs. 4. Identify the paired-difference variable.
A sample of 25 freshmen at a major university completed a survey that measured their degree of racial prejudice (the higher the score, the greater the prejudice) Compute the median and mean for these data? 10 43 30 30 45 40 12 40 42 35 45 25 10 33 50 42 32 38 11 47 22 26 37 38 10
A medical doctor is interested in determining whether mean body temperatures are different in the morning and at night. Five patients were recruited and their body temperatures were measured first at 8 AM and then again at 10 PM. The data is in the following table: Patient 1 2 4 Morning Night 98.0 97.6 97.2 97.0 98.0 97.0 98.8 97.6 97.7 98.8 For this matched pairs experiment, you should take the differences by calculating: Morning - Night. Also, you may use the fact that the sample standard deviation of 44/V5 the differences is 0.844 and that 0.844 0.3774. What is the test statistic for the test? Round your final answer to two decimals. Next Page Page 5 of 15 126 53 1. NOV 18
I often hear the opinion that "people who listen to classical music are smarter". In an attempt to test that claim, I gave an IQ test to twO groups of people: Group 1: Students who primarily listen to non-classical music. Group 2: Students who primarily listen to classical music. Their scores are summarized in the following table: Std. Deviation Group 1 111 Group 2 100 98 87 119 108 102 110 10.392 85 105 97 114 93 101 9.142 < Answer the question using a 0.10 level of significance. Select the response which fills-in-the-blank to create a correct sentence: Based on the information and previous parts of the problem, there listen to classical music tend to perform better on an IQ test than those who do not. evidence to support the claim that students who primarily is certain O is not sufficient O is sufficient O cannot be
