the hypothesis test and provide the test person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a 0.025 significance level to tes laim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation? ents portion of check | lumber lick here to view the chi-square distribution table. 0-24 62 25-49 9 he test statistic is Round to three decimal places as needed.)

*NOTE: This question was previously answered, but due to policy, only the first three parts could be answered. I am putting which parts were answered, and which parts still need answered. Thank you.    The accompanying table lists the numbers of words spoken in a day by each member of 56 different randomly selected couples. Complete parts​ (a) and​ (b) below.   A. Use a 0.05 significance level to test the claim that among​ couples, males speak fewer words in a day than females.       In this​ example, μd is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis​ test?           (Answered) H0​: μd ( =) 0 H1​: μd ( <) 0        (Answered) B. Identify the test statistic. t= -1.58         (Answered) C. Identify the​ P-value. ​P-value= 0.059   D. What is the conclusion based on the…

The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? E Click the icon to view the table. Determine the null and alternative hypotheses. O A. Ho: Whether a subject lies is independent of the polygraph test indication. H1: Whether a subject lies is not independent of the polygraph test indication. O B. Ho: Polygraph testing is not accurate. H1: Polygraph testing is accurate. O C. Ho: Polygraph testing is accurate. H1: Polygraph testing is not accurate. O D. Ho: Whether a subject lies is not independent of the polygraph test indication. H1: Whether a subject lies is independent of the polygraph test…

Among a simple random sample of 331 American adults who do not have a four-year college degree and are not currently enrolled in school, 159 said they decided not to go to college because they could not afford school.   A. Calculate the test statistic and the p-value.   B. State the conclusion in context.
