1.Find the specified areas for a standard normal distribution, and sketch the area.

a. The area to the left of z=-0.8

b. The area to the right of z=1.2

Find the specified areas for a standard normal distribution, and sketch the area.

a. The area to the right of z=2.58

b. The area to the left of z=-1.32

2.Suppose we want to test Ho: p=0.5 vs Ha: p>0.5 using a sample proportion of 520 out of 1000, 0.52

a.Use a randomization distribution to find the p-value:

b.What is the standard error from the randomization distribution? _____________ Model the randomization distribution with a normal distribution with mean 0.5 from the null hypothesis and standard deviation equal to this standard error. Find the p-value by finding the area to the right of 0.56 in this normal distribution.

c. Find the standardized test statistic. Then find the p-value by finding the area beyond this standardized value in a standard normal distribution.

d.Compare the 3 p-values
