Mr. Li is a math teacher at Pinkston High School who is preparing his students to take the SAT test. He collected data from 10 students who took the test last year and presented this information to the students in a table. Which linear regression equation best represents the line of best fit for the data if represents the number of hours spent studying? A y= 344.19x+22.54
B y= 344.19x−22.54
C y= 22.54x+344.19
D y= −22.54x+344.19

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
