D49 А B с D E K F G H 11. Which of the following examples would use the z-distribution: 2 3 X = 100; p = 99; s = 5; n = 70 4 X = 7; = 4; s = 1; n = 20 x = 50; p = 53; 0 = 7; n = 15 x = 15; p = 17; O = 3; n = 45 5 6 7 82. Know how to calculate point est., confidence interval, max , tolerable error. Know the effect when you change the 20 confidence level and the sample size. A high school surveyed their graduates on their starting salaries. 300 were returned. The average starting salary of the surveys returned was $32,000 with a standard deviation of $5,000. 12 13 14 15 16 What is the point estimate for the starting salary of 17 the graduates?

А B C D E F H 18 19 What is the 95% confidence interval for the average 20 salary of all graduates? Hint: Range 21 22 What is the value of the Maximum Tolerable Error 23 for the above confidence interval?? 24 Hint: This is the number that follows +/- in the confidence interval formula. You add it to and subrtact it from the mean! 25 26 27 28 If the level of confidence changes to 99%, and all 29 other variables remain unchanged, what will happen to the confidence interval??? 30 31 32 33 If the number of graduates returning the survey 34 changes from 300 to 700, all other variables 35 remaining unchanged, what will be effected??? (Probability of error? Point estimate? Confidence 37 Interval?) Hint: Only one changes! 36 38 39 3. Know how to calculate sample size: 40 Sheet1 Sheet2 Sheets F1 F2 80
3. Know how to calculate sample size: A restaurant would like to estimate the average $ amount of a 2 take-out order. The standard deviation is $15.
