Stat help please!!!!!

Find z such that 7.6% of the standard normal curve lies to the left of z.

Alison -

You need to find the answer to this ...

P(Z < z) = 0.076

Now simply look up the "area" 0.076 in the Standard Normal tables ...

z = -1.433

Say, for an easy way to find Standard Normal stuff, this website is great ...

Good luck with your Stats class!

Z tables show the area between the mean and a tail of the normal distribution, i.e 50% either side of the mean.
So area of 7.6% lying to the left of Z is shown in the tables as 50% - 7.6% = 42.4%
Look up 0.424 in the body of the table to find the Z value = 1.535
