You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test: Ho: p - 0.5 H:P. 0.5 A sample of 700 provided a sample proportion of 0.57. (a) Determine the standard error of the proportion. (Round your answer to five decimal places.) (b) Compute the value of the test statistic. (Round your answer to two decimal places.) (c) Determine the p-value, and using a = 0.05, test the hypotheses. Find the p-value. (Round your answer to four decimal places.) p-value= State your conclusion. O Do not reject H There is sufficient evidence to concludep differs from 05. O Reject H There is insufficient evidence to conclude p differs from 0.5. O Reject H There is sufficient evidence to conclude p differs from 0.5. O Do not reject Ha. There is insufficient evidence to conclude p differs from 0.

According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, Oregon had 714 complaints of identity theft out of 3449 consumer complaints. Does this data provide enough evidence to show that Oregon had a higher proportion of identity theft than 20%? Test at the 5% level. State the hypotheses. Họ: P ?v Ha: P ? Calculate the test statistic. Round to four decimal places. Calculate the standardized test statistic. Round to three decimal places. z = Find the p-value. Round to four decimal places. p-value = State your decision. O Since the p-value is less than .05, reject Ho. O Since the p-value is greater than .05, fail to reject Ho. O Since the p-value is greater than .05, reject Ho- O Since the p-value is less than .05, fail to reject Ho- Interpret the results. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Oregon is less than 20%. O At…

A news article that you read stated that 52% of voters prefer the Democratic candidate. You think that the actual percent is larger. 149 of the 266 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion  The null and alternative hypotheses would be:     Ho: ? p μ  Select an answer ≤ = < ≥ ≠ >   (please enter a decimal)    H1: ? p μ  Select an answer > ≥ ≤ = < ≠   (Please enter a decimal) The test statistic ? z t  =  (please show your answer to 3 decimal places.)
