In an experiment on extrasensory perception (ESP), a subject in one room is asked to state the color. |(red or blue) of a card chosen from a deck of 50 well-shuffled cards by anindividual in another room. Subject does't know how many are red/blue. If she identifies 32 cards correctly, are the results significant? 1.1 at a= 0.05 1.2. at a= 0.01 1.3. until what level of confidence? HINT: PROBLEM: Can the subject guess the color of more than 50% of the of the cards 1.4. Test the hypothesesthat the subject cannot guess more than 50% of the cards Hint: H1: p>0.5

A study was done to determine whether the proportion of women who had accidents on Friday the 13th was greater than the proportion of men who had accidents on Friday the 13th. To find out, a random sample was taken of 2,000 individuals. Each individual was asked their gender and whether they had been involved in an accident on Friday the 13th. a)What is the explanatory variable, and is it quantitative or categorical? b)What is the response variable, and is it quantitative or categorical? c)What procedure should be used for this test?

The accompanying table gives data from a survey of new car owners conducted by J.D. Power and Associates (USA TODAY, usatoday.com, March 29, 2016). For each brand of car sold in the United States, data on a quality rating (defects per 100 cars, so lower numbers indicate higher quality) and a customer satisfaction rating (called the APEAL rating) are given in the accompanying table. The APEAL rating is a score between O and 1000, with higher values indicating greater satisfaction.   Brand Quality Rating APEAL Rating Acura 64 814 Audi 80 858 BMW 76 849 Buick 74 792 Cadillac 58 826 Chevrolet 64 791 Chrysler 58 783 Dodge 58 790 Fiat 38 768 Ford 66 789 GMC 60 791 Honda 71 783 Hyundai 70 804 Infiniti 63 826 Jeep 43 762 Kia 72 791 Land Rover 55 853 Lexus 76 844 Lincoln 65 835 Mazda 74 790 Mercedes-Benz 67 842 MINI…

A warehouse manager wants to know if there is an association between the shift worked and being on time for work. To investigate, he selects a random sample of 70 workers and classifies each one according to the shift they worked most recently and whether they were on time for work. He was unable to classify a substantial number of people as being on time, so he classified those individuals as unknown. The data are displayed in the table.   The manager would like to know if these data provide convincing evidence of an association between the shift worked and being on time in the large population of all workers at this warehouse. The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 5, so all expected counts are at least 5. Yes, the smallest expected count is 8.54, so all expected counts are at least 5. No, the smallest expected count is 2.56, so the expected counts are not all at least 5. No, the smallest expected count is…

The effects of social skill training on a 29 year-old mentally retarded male adult were explored. The subject listened to typical social situations (such as getting a compliment or saying thank you) on audiotape and discussed the situations with a therapist. The subject's positive social verbal interactions were counted before the training, at three times during the training period, and at three times after the training had been completed. All counts were taken by observing the subject at a evening recreation time in the subject's group home. Results show that positive interactions increased during the training period but then rapidly decreased after training had stopped.

February 12, 2009 marked the 20oth anniversary of Charles Darwin's birth. To celebrate, Gallup, a national polling organization, surveyed 1,018 randomly selected American adults about their education level and their beliefs about the theory of evolution. In their sample, 325 of their respondents had some college education and 228 were college graduates. Among the 325 respondents with some college education, 133 said that they believed in the theory of evolution. Among the 228 respondents who were college graduates, 121 said that they believed in the theory of evolution. Construct a 90% confidence interval for the difference between the proportions of college graduates and individuals with some college who believe in the theory of evolution. Round your sample proportions and margin of error to three decimal places. O 0.012 to 0.232 O 0.038 to 0.206 O 0.052 to 0.192 O 0.079 to 0.165 Save for Later Attempts: 0 of 1 used Submit Answer

ific Calculator Of30shg/ckivdfk1p00003g5tgeftOid1 Agroup of researchers in New York wants to test if there is any relationship between living in California and preferring warm weather to cold weather. The researchers send out an online questionnaire to 200 randomly chosen people in the US asking several questions including: "Do you live in California?" and "Do you prefer warm weather to cold weather?". The results are summarized in the table below: Prefers Warm Weather 80 Prefers Cold Weather 42 Lives in California Doesn't Live in California 35 43 Test the null hypothesis that the choices on these two questions are independent versus the alternative that they are dependent. What are the p-value and conclusion of this test if the test is performed at the alpha =0.1 level? %3D p-value = 0.0091; Fail to reject the null hypothesis %3D p-value = 0.0039; Reject the null hypothesis p-value = 0.0039; Fail to reject the null hypothesis p-value = 0.0911; Reject the null hypothesis NEXT

Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) REsults from five of the students are includedin the graph. Use a significance level to test the claim that there is no difference between the reaction times on the right and left hands.What are the hypothesis for this test?What is the test satistic? Identify the Critical Value(s)What is the Conclusion?

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 311311 people over the age of​ 55, 6060 dream in black and​ white, and among 306306 people under the age of​ 25, 1212 dream in black and white. Use a 0.050.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts​ (a) through​ (c) below. a. Test the claim using a hypothesis test.
