A news article that you read stated that 56% of voters prefer the Democratic candidate. You think that the actual percent is larger. 142 of the 236 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance? For this study, we should use The null and alternative hypotheses would be: Ho: (please enter a decimal) H1: (Please enter a decimal) The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly larger 56% at αα = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger 56% The data suggest the population proportion is not significantly larger 56% at αα = 0.10, so…

Time magazine reported the result of a telephone poll adult Americans. The question posed of the Americans who were surveyed was: "Should the federal tax on cigarettes be raised to pay for health care reform?" The results of the survey were: Non-Smokers n1-395 Yes 272 Smokers n2 327 Yes 194 Calculate the appropriate test statistic, correct to two deomal places, to test whether Smokers and Non-Smokers differ significantly with respect to their opinions.

I need help asap. This is the question. A recent study at a local college claimed that the porportion, p, of students who commute more than 15 miles to school is no more than 15% . If a random sample of 175 students at this college is selected, and it is found that 86 commute more than 15 miles to school, can we reject the college's claim at the 0.05 level of significance. Perform 1 failed test then fill in the table below
