Test the claim by constructing an appropriate confidence interval.The 99% confidence interval is < (P1 - P2) Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 42 of the 48 subjects treated with echinacea developed rhinovirusinfections. In a placebo group, 93 of the 109 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effecton rhinovirus infections. Complete parts (a) through (c) below.

A poll conducted in 2013 found that 52% of U.S. adult Twitter users get at least some news on Twitter. The standard error for this estimate was 2.4%, and a normal distribution may be used to model the sample proportion.

A hypothesis test is performed at significance level a=0.05: The p-value is found to be 0.001. What can we conlcude? O Our dataset and statistical test proves that the null hypothesis it true. O The statistical test in inconclusive, and the dataset is neither evidence for or against any hypothesis. O none of these O Our dataset and statistical test leads us to believe the null hypothesis is true, but we cannot say for sure. Our dataset is evidence in support of the null hypothesis. O Our dataset and statistical test leads us to reject the null hypothesis. Our data is statistically significant evidence against the null hypothesis. O Our dataset and statistical test proves that the null hypothesis it false.
In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1 = not attractive; 10 = extremely attractive).

What does the confidence interval tell about the population of all adult females? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females. O B. We are 99% confident that the interval from to actually contains the true mean attractiveness rating of all adult females.…

Success In a survey, 1400 adults in a certain country were asked how many hours they worked in the previous week. Based on the results, a 95% confidence interval for me number of hours worked was lower bound 41.8 and upper bound: 45.8. Which of the following represents a reasonable interpretation of the result? For those that : not reasonable, explain the flaw. Complete parts (a) through (d) below. lia Libral Options ools O A. Flawed. This interpretation implies that the mean is only for last week. O B. Flawed. This interpretation makes an implication about individuals rather than the mean. O C. Flawed. This interpretation does not make it clear that the 95% is the probability that the mean is within the interval. O D. Correct This interpretation is reasonable. (d) We are 95% confident that the mean number of hours worked by adults in a particular area of this country in the previous week was between 41.8 hours and 45.8 hours. A. Flawed.

What if we're able to use a normal model. To construct a 95% Confidence Interval, we use the following formula: p hat ± ME for 95% CI If p hat = 0.38 and ME for 95% CI = 0.096, what is CI? Keep the numbers in 3 decimal places. Put the two numbers in ( ) and use a comma, then a space between the two numbers.
