A common design requirement is that an environment must fit the range of people who fall between the 5th percentile forwomen and the 95h percentile for men. In designing an assembly work table, the sitting knee height must be considered,which is the distance from the bottom of the feet to the top of the knee. Males have sitting knee heights that are normallydistributed with a mean of 21.2 in. and a standard deviation of 1.1 in. Females have sitting knee heights that are normallydistributed with a mean of 19.7 in. and a standard deviation of 1.0 in. Use this information to answer the following questions.What is the minimum table clearance required to satisfy the requirement of fitting 95% of men?23.0 in. (Round to one decimal place as needed.)Determine if the following statement is true or false. If there is clearance for 95% of males, there will certainly be clearancefor all women in the bottom 5%.A. The statement is false because the 95th percentile for men is greater than the 5th percentile for women.B. The statement is true because some women will have sitting knee heights that are outliers.C. The statement is true because the 95th percentile for men is greater than the 5th percentile for women.D. The statement is false because some women will have sitting knee heights that are outliers.The author is writing this exercise at a table with a clearance of 23.3 in. above the floor. What percentage of men fit thistable?96.56 % (Round to two decimal places as needed.) In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they couldsense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapiststo identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among300 trials, the touch therapists were correct 140 times. Complete parts (a) through (d)......a. Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responseswould be expected if the touch therapists made random guesses?0.5 (Type an integer or a decimal. Do not round.)b. Using Emily's sample results, what is the best point estimate of the therapists' success rate?0.467 (Round to three decimal places as needed.)c. Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made bytouch therapists.

An important issue in court cases is the accuracy of eyewitness testimony. Behavioral scientists have suggested eyewitnesses can be influenced by how a question is phrased. A researcher conducts a study where 15 people watch a film of an accident in which Car A runs a stop sign and hits Car B at a speed of 20 miles per hour. After watching the film, she asks each of the 15 people to estimate Car A's speed at the moment of impact (they do not know the actual speed). However, the question is phrased three different ways. Five people are asked, “How fast was Car A going at the time of the accident with Car B?” Another five are asked, “How fast was Car A going when it hit Car B?” The last five are asked, “How fast was Car A going when it smashed into Car B?” An investigator wants to determine if estimates of speed vary as a function of the wording of the question, with more extreme wordings leading to higher estimates, at 0.05 level. Let Xa be the group of people who were asked using the…

Can a person train to become better at holding their breath? An experiment was designed to find out. Twelve volunteers were randomly assigned to 1 of 2 groups. The 6 volunteers assigned to group 1 were given breath-holding exercises to perform for 2 weeks. The other group was not given any information about the experiment. At the end of the 2 weeks, all 12 volunteers were individually tested to determine how long they could hold their breath. Here are the data (in seconds). Group 1: 90, 88, 70, 110, 75, 105 Group 2: 40, 48, 35, 50, 55, 62 The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than volunteers without training. Let μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. What are the appropriate hypotheses? H0: μ1 – μ2…
A psychologist would like to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n = 5 in each sample. The rats in the first sample serve as a control and do not get any of the drug. The rats in the second group receive a small dose, and the rats in the third group each get a large dose of the drug. The psychologist records the activity level for each animal. The data from this experiment are presented below. no drug small dose large dose 2201O 22321 Complete the F-ratio table below.

Residents in a city are charged for water usage every three months. The water bill is computed from a common fee, along with the amount of water the customers use. The last water bills for 40 residents from two different neighborhoods are shown in the histograms below. Which of the following is a true statement comparing the water bills of the two neighborhoods? More homes on Front Street had water bills above $225 than on Pine Road. More homes on Pine Road had water bills under $150 than on Front Street. More homes on Pine Road had water bills above $200 than on Front Street. The same number of homes on both streets had water bills between $175 and $200.
Detergent manufacturers frequently make claims about effectiveness of their product. A consumer-protection service decided to test the five best selling brands of detergent in three water temperatures on their claim of producing the “whitest whites”. One hundred and fifty white sheets were equally soiled. Thirty sheets were washed in each of the five brands; 10 in cold water, 10 in warm water and 10 in hot water. After washing, the “whiteness” was measured with laser equipment. Perform the appropriate post-hoc analyses and clearly state your conclusions about the performance of the different brands in lukewarm water.

Women athletes at a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 36 women athletes at the school showed that 21 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 10% level of significance. Find the P-value of the test statistic. (Round your answer to four decimal places.) Sketch the sampling distribution and show the area corresponding to the P-value.
