Answer 9

So you're in the row which gives the probabilities corresponding to the zvalues between 1.6 and 1.7

Answer 10

Your goal is to locate the probability corresponding to the zvalue 1.67

Answer 11

Notice

1.67 = 1.6 + 0.07

Answer 12

gansh can you tell me what all the variables represent

Answer 13

http://prnt.sc/b1kqot that will help me process it

Answer 14

look in the row that starts with `1.6` (marked in red) and the column that has `0.07` up top (marked in green). It's the third from the right side

together, these row and columns combine to intersect. The value at this row and column combo is 0.95254

so the area to the left of z = 1.67 is approximately 0.95254

see attached

Answer 15

oh okay thanks. medals for both.

Answer 16

You won't understand this simply by knowing what the variables represent. This is statistics, not so easy. Are you skipping reading lessons and directly attempting homework?

Answer 17

to get the area to the right of z = 1.67, subtract the value in the table from 1

1 - (area to the left) = 1 - 0.95254 = 0.04746

so the area to the right of the z score is 0.04746 (approx)

Answer 18

ganeshie. this is a screenshot included in the lesson. i have not started the assessment.

Answer 19

\(\Large \mu\) = greek letter mu (lowercase) = population mean

\(\Large \sigma\) = greek letter sigma (lowercase) = population standard deivation

Answer 20

but i opened up the lesson and this is what it shot me with. im so confused.

Answer 21

Answer 22

Good good. Just making sure you don't take stats too light haha
