Page Question Answer 312 A If a binomial probability distribution satisfies the requirement where np 5 and nq 5 and if (-0.5<x<0.5), what is the formula for the ESTIMATED mean ( )? = np B What does the formula npq = represent? Standard deviation 314 If n = 213 and p = 0.5 A What does q equal? 0.5 B What is np 5 ? Required condition C What is the estimated mean? 106.5 D What is the estimated standard deviation? 7.297 315 Use the proper symbols (=,<, , >, ) For example x >122 A At least 122 122 B More than 122 > 122 C At most 122 122 D Fewer than 122 < 122 E Exactly 122 = 122 Paste your answer here: (10 points) Read chapter 6-7 and then answer the questions . Page Question Answer 324 to 325 A Which STATDISK graph is closer to depicting a normal distribution? (p. 324 or p. 325)? p. 324 B What is the problem with the STATDISK graph on page 325? The gap between each X values are too large. 328 To 329 A Which graph represents a population with a normal distribution? (#5 or #6)? #5 B Which graph represents a population with a normal distribution? ( # 7 or #8) ? #7 Paste your answer here: (2 points) 1 Chapter 6 PROBLEM 2: NOW ITS YOUR TURN! Find Z /2 using an 80% degree of confidence . First draw the bell curve and label it to show all four areas. I have set up the bell curve so that you can click inside and write the appropriate numbers. If for some reason that does not work, just write the areas in the table provided below the bell curve. (or do both ) L R .10 .40 .40 .10 R = Sum of areas to the left of R R = (0.10 + 0.40 + 0.40 = 0.90)R = (0....
