A poll of 2,039 randomly selected adults showed that 96% of them own cell phones. The technology display below results from a test of the claim that 94% of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and assume a 0.01 significance level to complete parts (a) through (e). Test of p=0.94 vs p≠0.94 Sample X N Sample p 95% CI Z-Value P-Value 1 1961 2,039 0.961746 (0.950804,0.972687) 4.13 0.000 a. Is the test two-tailed, left-tailed, or right-tailed? Left-tailed test Two-tailed test Right tailed test b. What is the test statistic? The test statistic is nothing. (Round to two decimal places as needed.) c. What is the P-value? The P-value is nothing. (Round to three decimal places as needed.) d. What is the null hypothesis and what do you conclude about it? Identify the null hypothesis. A. H0: p≠0.94 B. H0: p C. H0: p>0.94 D. H0: p=0.94 Choose the correct answer below. A. Reject the null hypothesis because the P-value is greater than the significance level, α. B. Reject the null hypothesis because the P-value is less than or equal to the significance level, α. C. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, α. D. Fail to reject the null hypothesis because the P-value is greater than the significance level, α. e. What is the final conclusion? A. there is not sufficient evidence to warrant rejection of the claim that 94 % of adults own a cell phone B.there is not sufficient evidence to support the claim that 94 % of adults own a cell phone C. A. there is sufficient evidence to warrant rejection of the claim that 94% of adults own a cell phone D. there is sufficient evidence to support the claim that 94% of adults own a call phone

A poll of

2,039

randomly selected adults showed that

96%

of them own cell phones. The technology display below results from a test of the claim that

94%

of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and assume a

0.01

significance level to complete parts (a) through (e).

Sample	X	N	Sample p	95% CI	Z-Value	P-Value
Test of p=0.94 vs p≠0.94
1	1961	2,039	0.961746	(0.950804,0.972687)	4.13	0.000

a. Is the test two-tailed, left-tailed, or right-tailed?

Left-tailed test

Two-tailed test

Right tailed test

b. What is the test statistic?

The test statistic is

nothing.

(Round to two decimal places as needed.)

c. What is the P-value?

The P-value is

nothing.

(Round to three decimal places as needed.)

d. What is the null hypothesis and what do you conclude about it?

Identify the null hypothesis.

H0: p≠0.94

H0: p<>

H0: p>0.94

H0: p=0.94

Choose the correct answer below.

Reject

the null hypothesis because the P-value is

greater than

the significance level,

α.

Reject

the null hypothesis because the P-value is

less than or equal to

the significance level,

α.

Fail to reject

the null hypothesis because the P-value is

less than or equal to

the significance level,

α.

Fail to reject

the null hypothesis because the P-value is

greater than

the significance level,

α.

e. What is the final conclusion?

A. there is not sufficient evidence to warrant rejection of the claim that 94 % of adults own a cell phone

B.there is not sufficient evidence to support the claim that 94 % of adults own a cell phone
