\[z = \frac{x - \mu}{\sigma}~~~~~~ z = \frac{500 - 544}{103}~~~and ~~~z = \frac{700-544}{103}\]

that's as far as I know

Answer 5

ty

Answer 6

could u guess on one of these questions for me?

Answer 7

similar for the next question

\[z = \frac{450 - 544}{103}\]

then use a table of values...

Answer 8

i cant find one

Answer 9

ok so calculate the z scores

\[\frac{500 - 544}{103} = -0.43\]

\[\frac{700 - 544}{103} = 1.51\]

so it looks like
