- Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 34 of the 39 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 98 of the 115 subjects developed rhinovirus infections. Use a 0.05 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. Identify the test statistic:Z= ___?____ Identify the P-Value: _______State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. _________Identify the confidence interval limits for the appropriate confidence interval.__?____ < P1-P2 < __?____In the population of senior students at Shermer High School, the proportion who plan to attend college is 0.64. In a random sample of 100 students from this population, the proportion who plan to attend college is 0.75. We would call the value 0.64 a P-value. z-score. parameter statistic significance level.If difference scores begin to pile up away from a sample mean difference score of MD = 0, which of the following statements is true? The null hypothesis will likely fail to be rejected. The null hypothesis will likely be rejected. The sample size is large. The critical region is small.

F = ? c. Calculate the test statistic. F = ? d. what is the correct decision?The Ministry of Health is interested in determining whether the average nicotine content of regular, menthol, and filtered cigarettes for 16different brands differ. The data from the sample is provided below. (see image attached) a. Define the null and alternative hypothesis for the ANOVA model. b. Calculate the missing values for the ANOVA table above. c. What is your conclusion for the ANOVA results?The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 pounds. Assuming that σis known to be 121.2 pounds, use a 0.10 significance level to test the claim that the population mean of all such employees weights is not equal to 200 pounds.
