- A survey about allergic reactions revealed that 84 out of randomly selected 158 people exhibit allergic symptoms. The percentage of the whole country is believed to be 25% for such allergic symptoms. Find the test statistic for hypothesis testing at right tail. (Sensitivity 0.00)Only 16% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 327 randomly selected registered voters surveyed, 56 of them will vote in the upcoming election. What can be concluded at the αα = 0.05 level of significance? For this study, we should use: z-test for a population proportion or t-test for a population mean The null and alternative hypotheses would be: H0:H0: ? μ p Select an answer ≠ < = > (please enter a decimal) H1:H1: ? p μ Select an answer > = ≠ < (Please enter a decimal) The test statistic ? z or t = (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 Select an answer: accept, reject or fail to reject the null hypothesis.

- 4) Estimate the difference between the proportion of females and males that are very satisfied from the rooms.5) Estimate the difference between the proportion of females and males that are very satisfied from the rooms with 95% confidence.6) Test at 0.01 significance level if the proportion of females that are very satisfied from the rooms is same as that of males.Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 363 randomly selected registered voters surveyed, 91 of them will vote in the upcoming election. What can be concluded at the αα = 0.01 level of significance? 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 higher than 19% at αα = 0.01, 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 19%. The data suggest the population proportion is not significantly higher than 19% at αα = 0.01, so there is statistically significant evidence to conclude that the percentage of registered voters who will…According to the Center for Disease Control and Prevention, the percentage of children age 6-11 years in the U.S. who are obese is greater than 18%. In a random sample of 1000 kids age 6-11 years, 220 were found to be obese. Using a complete test of hypothesis with a = 0.05 , is there enough evidence to support the claim of the Center for Disease Control and Prevention? List the steps required for a test of hypothesis.
