- Only 13% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 364 randomly selected registered voters surveyed, 55 of them will vote in the upcoming election. What can be concluded at the α 0.10 level of significance? For this study, we b. The null and alternative hypotheses would be: a. For this study, we should use Select an answer (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) c. The test statistic? '-! d. The p-value e. The p-value is ? f. Based on this, we should Select an answer g. Thus, the final conclusion is that Please show your answer to 4 decimal places.) the null hypothesis. The data suggest the populaton proportion is significantly higher than 13% at α = 0.10, so there is statistically significant evidence to conclude that the the percentage of all registered voters who will vote in the upcoming election will be higher than 13%.

Ho: u 2 600 HaiH 600 Но: и 3D 600 Ha: u + 600 The hypotheses Ho: µ 2 600 and H: µ 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is less than or equal to 600 and find evidence to support u > 600. The hypotheses Ho: u = 600 and H: µ + 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is equal to 600 and find evidence to support u + 600.

A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 302 people from the inner city surveyed, 36 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05?
