Consider the following hypotheses:
H0: p ≥ 0.48
HA: p < 0.48
Compute the p-value based on the following sample information. (You may find it useful to reference the appropriate table: z table or t table) (Round "z" value to 2 decimal places. Round intermediate calculations to at least 4 decimal places and final answers to 4 decimal places.)
| p-value | ||||
| a. | x = 50; n = 122 | |||
| b. | x = 118; n = 329 | |||
| c. | p⎯⎯p¯ = 0.42; n = 41 | |||
| d. | p⎯⎯p¯ = 0.42; n = 413 | |||
Solution:

a)


The p-value is p = 0.0604
--------------------------------------------------------------------------------------------------------------------
b)

The p-value is p = 0
----------------------------------------------------------------------------------------------------------------
c)

The p-value is p = 1
------------------------------------------------------------------------------------------------------------
d)

The p-value is p = 0
