Question

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Upper H 0H0: p equals=0.3 versus Upper H 1H1: p greater than>0.3 n equals=125; x equals=43; alphaαequals=0.1

Answer #1

Solution :

This is the right tailed test .

The null and alternative hypothesis is

H_{0} : p = 0.3

H_{a} : p > 0.3

= x / n = 43 / 125 = 0.344

Test statistic = z

=
- P_{0} / [P_{0
*} (1 - P_{0} ) / n]

= 0.344 - 0.3 / [(0.3 * 0.7) / 125]

= 1.0735

P-value = 0.1415

= 0.1

P-value >

Fail to reject the null hypothesis .

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. Upper H 0: p equals 0.6
versus Upper H 1: p greater than 0.6 ; n equals 100; x equals
650, alpha equals 0.1

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.
Upper H 0=0.6
versus
Upper H1: >0.6
n=200;
x=125,
alphaα=0.1

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
Upper H 0H0:

1) Calculate the test statistic, Z0
2) Identify the P Value
3)Choose the correct result:
- Do not reject the null hypothesis; b/c the p value is less
than α
-Do not reject the null hypothesis; b/c the p value is greater
than α
- Reject the null hypothesis; b/c the...

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. Upper H 0 : p equals 0.88
versus Upper H 1 : p not equals 0.88 n equals 500 comma x equals
430 comma alpha equals 0.1

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
H 0 : p equals 0.61 versus Upper H 1 : p less than 0.61 H0:
p=0.61 versus H1: p<0.61
n equals 150 comma x equals 87 comma alpha equals 0.1n=150,
x=87, α=0.1
what is the P value?
