According to a polling organization, 23% of adults in a large region consider themselves to be liberal. A survey asked r
Identify the null and alternative hypotheses for this test. Let p represent the population proportion of adults in this region who consider themselves to be liberal. OA. Hop<0.23 H₁: p=0.23 OD. Ho: p=0.23 H₁: p=0.23 OB. Ho: p=0.23 H₁: p<0.23 OE. Ho: p=0.23 H₁: p>0.23 OC. Ho:p>0.23 H₁: p=0.23 OF. H₂: p=0.23 H₁: p=0.23
Find the test statistic for this hypothesis test. (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. (Round to three decimal places as needed.)
State the conclusion. OA. Reject Ho. There is not sufficient evidence at the a= 0.01 level of significance to conclude that the proportion is higher than that reported by the polling organization. OB. Do not reject Ho. There is not sufficient evidence at the a=0.01 level of significance to conclude that the proportion is higher than that reported by the polling organization.
OC. Reject Ho. There is sufficient evidence at the a=0.01 level of significance to conclude that the proportion is higher than that reported by the polling organization. OD. Do not reject Ho. There is sufficient evidence at the a=0.01 level of significance to conclude that the proportion is higher than that reported by the polling organization.
