When 3005 adults were surveyed in a poll, 22% said that they use the Internet. Is it okay for a newspaper reporter to write that "1/4 of all adults use the Internet"? Why or why not? Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.25 H,:p<0.25 O B. Ho: p= 0.25 H,: p#0.25 OC. Ho: p= 0.75 H;: p>0.75 O D. Ho: p=0.75 H,: p#0.75 O E. Ho: p=0.75 H,: p<0.75 OF. Ho: p=0.25 H,: p>0.25 The test statistic is z= (Round to two decimal places as needed.) The P-value is (Round to four decimal places as needed.) Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim. (Assume a 0.05 significance level.) V Ho. There V sufficient evidence to warrant rejection of the claim that 1/4 of all adults use the Internet. The reporter should not write that 1/4 of all adults use the Internet.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

When 3005 adults were surveyed in a poll, 22% said that they use the Internet. Is it okay for a newspaper reporter to write that "1/4 of all adults use the Internet"? Why or why not?
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value
method. Use the normal distribution as an approximation of the binomial distribution.
Identify the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: p=0.25
H,: p<0.25
O B. Ho: p= 0.25
H;: p#0.25
O C. Ho: p= 0.75
H,: p> 0.75
O D. Ho: p=0.75
H,: p#0.75
O E. Ho: p= 0.75
H,: p<0.75
OF. Ho: p 0.25
H,: p>0.25
The test statistic is z =
(Round to two decimal places as needed.)
The P-value is
(Round to four decimal places as needed.)
Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim. (Assume a 0.05 significance level.)
Ho. There
sufficient evidence to warrant rejection of the claim that 1/4 of all adults use the Internet. The reporter should not write that 1/4 of all adults use the
Internet.
