13.11 Do social robots walk or roll? Refer to the InternationalConference on Social Robotics (Vol. 6414, 2010) study ofhow engineers design social robots, Exercise 2.7 (p. 38).Recall that a social (or service) robot is designed to enter-tain, educate, and care for human users. In a random sam-ple of 106 social robots obtained through a Web search, theresearchers found that 63 were built with legs only, 20 withwheels only, 8 with both legs and wheels, and 15 with neitherlegs nor wheels. Prior to obtaining these sample results, arobot design engineer stated that 50% of all social robotsproduced have legs only, 30% have wheels only, 10% haveboth legs and wheels, and 10% have neither legs nor wheels.a. Explain why the data collected for each sampled socialrobot are categorical in nature.b. Specify the null and alternative hypotheses for testing thedesign engineer's claim.c. Assuming the claim is true, determine the number ofsocial robots in the sample you expect to fall into eachdesign category.d. Use the results to compute the chi-square test statistic.e. Make the appropriate conclusion using a = .05.

An experiment was conducted to compare the effectiveness of four training programs, namely, A, B, C, and D in training assemblers of a piece of electronic equipment. Twenty employees were randomly selected and assigned to each program, that is, five employees per program. After completion of the training courses, each person was required to assemble four pieces of equipment, and the length of time (in secs) to complete the assembly was recorded. The summary of the data gathered is recorded in the table. At α=0.10, test for the hypothesis that the assembly times for people trained are the same for the four programs.

6.1 Sexual harassment of college students. A survey of 2036 undergraduate college students aged 18 to 24 reports that 62% of college students say they have encountered some type of sexual harassment while at college.1 Describe the sample and the population for this setting 6.4 How often do they play? In the Pew survey described in Example 6.1, those who played video games were asked how often they played. In this subpopulation, 223 adults said that they played every day or almost every day 6.10 How often do they play? Refer to Exercise 6.4 (page 318). (a) Find SE^p, the standard error of ^p. (b) Give the 95% confidence interval for p in the form of estimate plus or minus the margin of error. (c) Give the confidence interval as an interval of percents.
A college student is interested in whether presoaking time has an effect on cleanliness of clothing. He collects the dirty clothes from all of the people in his dorm and randomly assigns clothing to one of four presoak time conditions: 5 minutes, 10 minutes, 15 minutes, 20 minutes. He then asks members of another dorm to rate the cleanliness of the items (they don’t know which clothing got which soaking time). The data are presented below. A) Perform an ANOVA by hand (SHOW ALL OF YOUR WORK by taking a photo of your handwork and either inserting it into the word document or uploading it as a separate file.) B) ANSWER QUESTION: Did the college student reject the null hypothesis? (yes or no)

A recent PwC survey of 1,379 CEOs from a wide range of industries representing a mix of company sizes from Asia, Europe, and the Americas indicated that CEOs are firmly convinced that it is harder to gain and retain people's trust in an increasingly digitalized world (pwc.to/2jFLzjF). Fifty-eight percent of CEOs are worried that lack of trust in business would harm their company's growth. Which risks arising from connectivity concern CEOs most? Eighty-seven percent believe that social media could have a negative impact on the level of trust in their industry over the next few years. But they also say new dangers are emerging and old ones are getting worse as new technologies and new uses of existing technologies increase rapidly. CEOs are particularly anxious about breaches in data security and ethics and IT outages and disruptions. A vast majority of CEOs are already taking steps to address these concerns, with larger-sized companies doing more than smaller-sized companies. a.…
A car dealer randomly selects 24 automatic cars and 21 manual cars to compare the fuel efficiency of the engines. A dotplot of the data is shown below, where each dot represents the fuel efficiency of one car (km/l) in the sample (greater fuel efficiency is indicated by larger numbers). Choose TWO options that best describes what the graph tell you about the fuel efficiency of the cars in the sample: a) fuel efficiency for manual cars is positively skewed. b) manual cars have the higher median fuel efficiency. c) the least fuel efficient car in the sample is manual. d) the most fuel efficient car in the sample is automatic. e) automatic have the larger range. d) fuel efficiency for manual cars is negatively skewed.
The characteristics of check teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The check teeth of an extinct primate species was the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). A total of 18 check teeth extracted from skulls discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderate-heavy, or heavy). The 18 measurements are listed here. Data on Degree of Wear Unknown Slight Unknown Slight Unknown Heavy Moderate Unknown Slight Light-moderate Unknown Light-moderate Moderate-heavy Moderate Moderate Unworn Slight Unknown Identify the variable measured in the study and its type (qualitative and quantitative) Form frequency distribution. Identify the degree of wear category that occurred most often in the sample of 18 check teeth.

4) Media Research Inc. conducted a study of the radio habits of urban and rural listeners. One facet of the study involved a participant’s listening time per day. a) State the Hypothesis to show the variation in the listening time depends on residence (urban or rural). b) Media Research Inc. collected the number of minutes spent listening to the radio in a day for a random sample of 10 urban and 11 rural listeners. The data appears below. Use JMP software to test the hypothesis of part a). c) Using aplha= 0.05, draw a conclusion for the hypothesis test and state the conclusion in the context of the problem.

The article "Prediction of Performance and Evaluation of Flexible Pavement Rehabilitation Strategies" (K. Lee, K. Wilson, and S. Hassan, Journal of Traffic and Transportation Engineering, 2017:178–184), describes methods used to rehabilitate Route 165 in the town of Exeter, Rhode Island. The following table presents monthly counts of two-axle and five- axle trucks during a recent year. The results are presented in the following table. Month Two-axle Five-axle Difference January 1168 1301 -133 February 1466 1495 -29 March 1389 1966 -577 2136 April May 1691 -445 2116 2015 101 June 2109 2180 -71 2115 July August September 2432 317 2523 2064 459 2408 2234 174 October 1899 2144 -245 November 1296 1781 -485 December 1333 1625 -292 Can you conclude that the monthly means differ between the two types of trucks?
