Question

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

Answer #1

Solution :

This is the two tailed test .

The null and alternative hypothesis is

H_{0} : p = 0.88

H_{a} : p
0.88

= x / n = 430 / 500 = 0.860

Test statistic = z

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

= 0.86 - 0.88/ [(0.88 * 0.12) / 500]

= -1.376

P(z < -1.38) = 0.0838

**P-value = 0.1676**

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 0.88H0: p=0.88 versus H1: p≠0.88 n
equals 500 comma x equals 430 comma alpha equals 0.01n=500, x=430,
α=0.01

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?

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 : p equals 0.62
versus Upper H 1 : p less than 0.62 n equals 150 comma x equals 81
comma alpha equals 0.01 Is np 0 left parenthesis 1 minus p 0 right
parenthesis greater than or equals 10? No Yes Your answer is
correct. Use technology to find the P-value. P-value= nothing
(Round to three decimal places as needed.)

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
Upper H 0 : p = 0.89 versus Upper H 1 : p not equals 0.89
n=500, x=430, a=0.01
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.)

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

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
Upper H 0 : p equals 0.61 versus Upper H 1 : p less than 0.61H0:
p=0.61 versus H1: p<0.61
n equals 150 comma x equals 84 comma alpha equals 0.01n=150,
x=84, α=0.01
