> Question 9 3 pts In a randomized, double-blind, placebo-controlled trial of children, echinacea was tested as a treatment for upper respiratory infections in children. "Days of fever" was one criterion used to measure effects. Among 337 children treated with echinacea, the mean number of days with fever was 0.81, with a standard deviation of 1.50 days. Among 370 children given a placebo, the mean number of days with fever was 0.64 with a standard deviation of 1.16 days. Assuming...

Part 7 Several countries in Africa have implemented a programme to supply insecticide- treated bed nets to communities in which there was a high prevalence of malaria in young children. A study was carried out to estimate the impact of the programme and determine whether the prevalence of malaria in young children was lower in countries that had implemented the programme. Researchers randomly sampled households from a country that had implemented the programme (country A) and a country that had...

In a randomized double-blind, placebo-controlled trial of children, an herb was tested as a treatment for upper respiratory infections in children. "Days of fever was one criterion used to measure effects. Among 335 children treated with the herb, the mean number of days with fever was 0.78, with a standard deviation of 1.51 days. Among 387 children given a placebo, the mean number of days with fever was 0.56 with a standard deviation of 123 days. Usea 0.01 significance level...

Problem 7: In a randomized controlled trial conducted with children suffering from a viral cough, 46 children were treated with low humidity while 46 other children were treated with high humidity. Researchers used a standard cough score to assess the results after an hour of treatment. The low- humidity group had a mean score of 0.98 with a standard deviation of 1.22, while the high-humidity group had a mean score of 1.09 with a standard deviation of 1.11. Use a...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
