Home/Mathematics/The following data resulted from a taste test of two different chocolate bars. The first number is a rating of the taste, which could range from 0 to 5, with a 5 indicating the person liked the taste. The second number indicates whether a "secret ingredient was present. If the ingredient was present, a code of "1" was used and, if not, a "0" otherwise. At the 0.01 significance level, do these data show a difference in the taste ratings?

ROBOTS 2.78 Do social robots walk or roll? Refer to the International Conference on Social Robotics (Vol. 6414, 2010) study on the current trend in the design of social robots, Exercise 2.5 (p. 48). Recall that in a random sample of social robots obtained through a Web search, 28 were built with wheels. The number of wheels on each of the 28 robots is listed in the accompanying table 4 4 3 3 3 6 4 2 2 2 1 3 3 3 4 4 3 4 3 2 8 2 2 3 4 3 2 3 Source Based on S.

Background An important element in a lawsuit is “discovery” where the parties are required to share with each other documents relevant to the dispute. Excluded from such disclosure obligation are documents in which a claim of solicitor-client privilege are claimed. In a lawsuit, the Office of the Information and Privacy Commissioner of Alberta (OIPC) ordered the production of records over which the University of Calgary had claimed solicitor-client privilege. The University provided a list of documents indicating solicitor-client privilege had been asserted over the records. The OIPC issued a Notice to Produce Records under s. 56(3) of the Freedom of Information and Protection of Privacy Act which requires a public body must produce required records to the Commissioner “[d]espite . . . any privilege of the law of evidence”. The University disputed the release of the privileged documents. Question Please advise what the Supreme Court of Canada decided about S. 56(3) of the Freedom of Information and Protection of Privacy Act and whether it applied to the privileged documents.
1) Definition of accuracy and precision: a. Accuracy in an experiment describes: i. How close your experimental values match your theoretical or predicted value. ii. How close multiple measurements of the same value are to each other. 2) Precision in an experiment describes: i. How close your experimental values match your theoretical or predicted value. ii. How close multiple measurements of the same value are to each other.
Solve (i) 3x = 7 mod 11, (ii) 7x + 3 = 1 mod 31, (iii) 13x = 12 mod 100.
