Answer #1

​(a) Z = 1.68

The p-value for Z = 1.68 is 0.9535. [From the z-table for Z = 1.68]

The graph is:

​(b) Z = 0.64

The p-value for Z = 0.64 is 0.7389. [From the z-table for Z = 0.64]

The graph is:

​(c) Z = -1.52

The p-value for Z = -1.52 is 0.0643. [From the z-table for Z = -1.52]

The graph is:

and ​(d) Z= -0.51

The p-value for Z = -0.51 is 0.3050. [From the z-table for Z = -0.51]

The graph is:

Please give me a thumbs-up if this helps you out. Thank you!
