- A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterarguement? A. Even 0.08 degrees is a lot and thus should be considered. B. The margin of error is just extra information and thus can be ignored. C. The difference with any previous decade is much greater than the margin of error. D. 0.15 - 0.08 is 0.07, which is still an increase and thus should be considered.Suppose 60 percent of the customers at Pizza Palooza order a square pizza, 80 percent order a soft drink, and 48 percent order both a square pizza and a soft drink.

- 1. The rent of a condo unit was ₱1,200.00 for one night, to be shared equally by a group of female friends, who will be having their get together in the condo unit. At the last minute, four people decided not to go to the party, thus raising the cost to each girl by ₱400.00. How many girls attended the get-together? 2. Joy went to her province with her van, driving 300 km at a certain average speed. Had she traveled 10 kilometers per hour, the trip would have taken 1 hour less. Compute for Joy’s average rate.Of the high blood pressure patients in a particular clinic, 62% are treated with medicationX, the remainder with medication Y. No patient is given both medications. It is known that 1.4% of thepatients using medication X suffer from fainting episodes, as do 2.9% of the patients using medicationY. A patient known by the clinic to have high blood pressure suffers a fainting episode, but she doesnot know which medication she is on. Which medication is she most likely taking?A friend who lives in Los Angeles makes frequent consultingtrips to Washington, D.C.; 50% of the time shetravels on airline #1, 30% of the time on airline #2, and the remaining 20% of the time on airline #3. For airline#1, flights are late into D.C. 30% of the time and late intoL.A. 10% of the time. For airline #2, these percentagesare 25% and 20%, whereas for airline #3 the percentagesare 40% and 25%. If we learn that on a particular trip shearrived late at exactly one of the two destinations, whatare the posterior probabilities of having flown on airlines#1, #2, and #3? Assume that the chance of a late arrival inL.A. is unaffected by what happens on the flight to D.C.[Hint: From the tip of each first-generation branch on atree diagram, draw three second-generation brancheslabeled, respectively, 0 late, 1 late, and 2 late.]
