Question

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

Answer #1

Solution:

Here, we have to use z test for population proportion.

H_{0}: p = 0.6 versus H_{1}: p > 0.6

This is an upper tailed test.

We are given α = 0.1

Test statistic formula for this test is given as below:

Z = (p̂ - p)/sqrt(pq/n)

Where, p̂ = Sample proportion, p is population proportion, q = 1 - p, and n is sample size

x = number of items of interest = 125

n = sample size = 200

Sample size is adequate to use normal approximation.

p̂ = x/n = 125/200 = 0.625

p = 0.6

q = 1 - p = 0.4

Z = (p̂ - p)/sqrt(pq/n)

Z = (0.625 – 0.6)/sqrt(0.6*0.4/200)

Z = 0.7217

P-value = 0.2352

(by using z-table)

P-value > α = 0.1

So, we do not reject the null hypothesis

There is not sufficient evidence to conclude that the population proportion is greater than 0.6.

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 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=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

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

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= 0.7 versus
Upper H 1 ?: p> 0.7n= 125?; x= 93?, alpha equals0.01

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: 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.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. Upper H 0 : p = 0.5 versus
Upper H 1 : p < 0.5 n=250, x=130, α=0.01 What is the
P-value?
