In order to test the effectiveness of the Flu vaccine, it was administered to 600 people who were selected at random. At the end of the Flu season it was determined that 504 individuals did not get the Flu. Then the 95% confidence interval for the true proportion p of individuals who develop immunity is given by0.84 ± 0.05
0.84 ± 0.029
0.84 ± 1.96
0.84 ± 0.196

Suppose that 600 students we selected at random from a student body and given a vaccine to prevent a certain type of flu. The campus reported cases of the flu so the students were exposed. A follow-up survey found that 562 of them did not get the flu. a. Calculate the sample estimate of the proportion of the shot being successful. b. Construct a 95% confidence interval around the sample estimate. This is a proportion and all the information you...

A laboratory is testing a new vaccine against virus Z. It is administered to 500 subjects (treatment group). Another 500 subjects were selected and given no vaccine (control group). After 5 months, they found that 20 subjects from the treatment group and 70 subjects from the control group were infected with the virus Z. (A) What's the probability of getting the virus if no vaccine was given? Calculate the confidence interval of the estimate. (Use 95% C.I.) (B) If the...

In a recent poll, 600 people were asked if they liked soccer, and 10% said they did. Based on this, construct a 90% confidence interval for the true population proportion of people who like soccer. As in the reading, in your calculations: --Use z = 1.645 for a 90% confidence interval --Use z = 2 for a 95% confidence interval --Use z = 2.576 for a 99% confidence interval. Give your answers as decimals, to 4 decimal places. [________, ________]

Information: Flu season comes every year and it is time to look at who in our community is most likely going to get us sick. Using a representative sample of the general population in the United States, we have constructed a table that shows flu vaccination status by age group. People were categorized as vaccinated for the 2015 flu season if they received influenza vaccine between September and November of 2014. Since we are confident in the representativeness of our...

The Bacille Calmette Guerin (BCG) vaccine is said to provide decades of protection against tuberculosis (TB). To test this theory, a researcher takes a random sample of 189 individuals who have been vaccinated with BCG and 322 individuals who have not been vaccinated with BCG. Out of those who were vaccinated, 16 became infected with TB. Out of those who were not vaccinated, 68 were infected with TB. The researcher is testing p1 = “the proportion of TB infected individuals...

The probability that a person will develop dementia over their lifetime is 0.004. Researches conducted a random sample of 3000 people and determined that 17 of them developed dementia. Is there evidence to support the claim that the true proportion of people who will develop dementia is different from 0.004 at the α = 0.05 level of significance? 1. Determine what the null and alternative hypotheses is: Ho: H1: 2. Which type of test is conducted in the problem? 3....
