Suppose that we have a problem for which the null and alternative hypothesis are given by:

H₀: = 660.

H₁: > 660.

Is this a right-tailed test, left-tailed test, or two-tailed test. Find the z value based on a level of significance of =.05.

It is important to note that this is a right-tailed test. Therefore, we want to find a z that satisfies:

P(Z>z)=.05.

It is easier to find the equivalent z that satisfies P(ZCorresponding to a probability of .95, we find on the standard normal chart that, approximately, z=1.64.According to how they found this answer, I need help figuring out which chart gets me this answer, I know I am using the wrong chart.
