I need help with my last question

Search forums Homework 2 - due Tuesday, September 20 Question A. Fill out a table like the one below, but using your birth date in column X and the first 8 digits of your Student ID number in column Y. (In the numbers....) example below, I use my birth date and the first 8 digits of a hypothetical student ID number. Don't use these numbers! Use your own Birth date: 03-31-1966 (all 8 digits are in column X) variance - ID number. 973123456 (the first 8 digits are in column Y ; drop the last digit of the ID number) (1- 3)- + (1- 3)2 + (2- 3)2 + 10- 3)2+ X = birth date digits Y = ID number digits (1-3)2 + (9-3)2 + ( 9- 3)2+ ( 1-3) 2 first number 36 36 4 9 second 98 /4 = 12.25 number 3 third number 0 Sed Dey = FNNWWO - fourth 12. 25 - 17- 265 number = 3.5 = 2 0 69 # 2.70 fifth number 2 sixth number 3 a . mearx 3 a meany = 3 add 24 / 8 = mean 24/8 = 3 seventh number 6 1 Variancex = 12. 25 Variancey = 7.265 eighth number 10 SedDey = 3 . 5 Still Devs 2. 70 2- Score (X ) -57 REMEMBER, DO NOT USE THE NUMBERS IN THE TABLE ABOVE.

Convert each of the scores in the X column into its corresponding z-score. Round to 2 decimal places. 0 -3 = -3/3.5=-.86 c. Calculate meany , vary and sidDevy. Round to 2 decimal places. 1- 3 = -2/3, 52 -57 d. Convert each of the scores in the Y column into its corresponding z-score. Round to 2 decimal places. 9- 3 = 6/3. 5 =171 9 - 3 = 1315= 1.71 Then, answer the following questions 1 - 3 = 13.5 =-157 1.
