Question

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test.

Upper H 0 : p equals 0.85 versus Upper H 1 : p not equals 0.85H0: p=0.85 versus H1: p≠0.85

n equals 500 comma x equals 410 comma alpha equals 0.01n=500, x=410, α=0.01

Is

np 0 left parenthesis 1 minus p 0 right parenthesis greater than or equals 10np01−p0≥10?

Select the correct choice below and fill in the answer box to complete your choice.

(Type an integer or a decimal. Do not round.)

A.No, because

np 0 left parenthesis 1 minus p 0 right parenthesisnp01−p0equals=nothing.

B.Yes, because

np 0 left parenthesis 1 minus p 0 right parenthesisnp01−p0equals=nothing.

Now find

ModifyingAbove p with caretp.

ModifyingAbove p with caretpequals=nothing

(Type an integer or a decimal. Do not round.)Find the test statistic

z 0z0.

z 0z0equals=nothing

(Round to two decimal places as needed.)

Find the P-value.

P-valueequals=nothing

(Round to three decimal places as needed.)

State the conclusion of the hypothesis test.

▼

Reject the null hypothesis,

Do not reject the null hypothesis,

because the P-value is

▼

greater

less

than

alphaα.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.

because the P-value is ▼ less greater than alpha.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. Upper H 0: p=0.6 versus Upper
H 1: p greater than0.6 n=100; x=65, alpha=0.1 Is np 0 left
parenthesis 1 minus p 0 right parenthesis greater than or
equals10?

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.

p value (round to three decimal places)=
(reject or do not reject?) the null hypothesis because the p
value is (greater or less) than x.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
H 0: 0.6 versus H 1: p > 0.6
n =100; x= 65, alpha=0.1 Is np 0 (1- p 0) greater than or
equals 10? *No OR Yes? *
Use technology to find the P-value. *P-value= ?* (Round to
three decimal places as needed.)
*Reject OR Do not* reject the null hypothesis,
because the P-value is *greater OR less* than alpha.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
Upper H 0 : p = 0.93 versus Upper H 1 : p not equals 0.93
n=500, x=450, a=0.05
Now find p ^ (Type an integer or a decimal. Do not
round.)
Find the test statistic z0. (Type an integer or a decimal. Do
not round.)
Find P-value (Type an integer or a decimal. Do not round.)
