One study, based on responses from 1,011 randomly selected teenagers, concluded that 41% of teenagers cite grades as their greatest source of pressure. Use a 0.05 significance level to test the claim that fewer than half of all teenagers in the population feel that grades are their greatest source of pressure. Formulate the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.5 OB. Ho: p=0.5 Ha: p<0.5 Ha: p > 0.5 O C. Ho: p=0.5 Ha: p *0.5 O D. Ho: p<0.5 Ha: p=0.5 Find the test statistic. z= (Round to two decimal places as needed.) Find the P-value for the found test statistic. P-value = (Round to four decimal places as needed.) State the conclusion. Choose the correct answer below. O A. Reject Ho. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure. B. Do not reject Ho. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure.

Question
Transcribed Image Text:One study, based on responses from 1,011 randomly selected teenagers, concluded that 41% of teenagers cite grades as their greatest source of pressure. Use a
0.05 significance level to test the claim that fewer than half of all teenagers in the population feel that grades are their greatest source of pressure.
O
Formulate the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: p=0.5
O B. Ho: p=0.5
Ha: p>0.5
Ha: p<0.5
O C. Ho: p=0.5
O D. Ho: p<0.5
Ha: p=0.5
Ha: p=0.5
Find the test statistic.
Z= (Round to two decimal places as needed.)
Find the P-value for the found test statistic.
P-value= (Round to four decimal places as needed.)
State the conclusion. Choose the correct answer below.
O A. Reject Ho. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source
of pressure.
O B. Do not reject Ho. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest
source of pressure.
