###### Question details

SET THREE:

Chapter 6, Section 1-HT,

Exercise 046 Use the normal distribution and the given sample
results to complete the test of the given hypotheses. Assume the
results come from a random sample and use a 5% significance
level.

Test H0 : p=0.5 vs Ha : p>0.5 using the sample results p^=0.60
with n=25 Round your answer for the test statistic to two decimal
places, and your answer for the p-value to three decimal
places.

test statistic = ________________

p-value = ____________________

Conclusion: (Choose the answer from the menu)

Reject OR Do not reject H0.

SET FOUR:

Chapter 6, Section 4-D, Exercise 180

Use the formula to find the standard error of the distribution of
differences in sample means, x¯1-x¯2. Samples of size 115 from
Population 1 with mean 92 and standard deviation 14 and samples of
size 75 from Population 2 with mean 78 and standard deviation
17

Round your answer for the standard error to two decimal
places.

standard error = ____________ (the absolute tolerance is
+/-0.01)
