In a randomized controlled trial in Kenya, insecticide-treated bednets were tested as a way to reduce malaria. Among 343 infants using bednets, 15 developed malaria. Among 294 infants not using bednets, 27 developed malaria. Want to use a 0.01 significance level to test the claim that the incidence of malaria is lower for infants using bednets. Find the test statistic. (Round to the nearest hundredth) (ONLY TYPE IN THE NUMBER!)

. In a randomized controlled trial, insecticide-treated bednets were tested as a way to reduce malaria. Among 332 infants using bednets, 15 developed malaria. Among 270 infants not using bednets, 22 developed malaria. Use a 0.05 significance level to test the claim that the incidence of malaria is lower for infants using bednets. Do the bednets appear to be effective? Conduct the hypothesis test by using the results from the given display. Difference= p(1)-p(2) Estimated for difference: -0.0363008 95% upper...

In a randomized controlled trial in Kenya, insecticide treated bed nets were tested as a way to reduce malaria. Among 343 infants using bed nets, 15 developed malaria. Among 294 infants not using bed nets, 27 developed malaria (based on data from “Sustainability of Reductions in Malaria Transmission and Infant Mortality in Western Kenya with use of insecticide treated bed nets, Journal of the American Medical Association, Vol. 291, No. 21) a) Construct a 99% confidence interval for the difference...

In a controlled laboratory environment, independent random samples of 10 adults and 10 children were tested by a psychologist to determine the room temperature that each person finds most comfortable. The study provided the following results: Adults Children Sample size 10 10 Sample mean (in degrees) 77.5 74.5 Sample variance 4.5 2.5 Which one of the following is the correct 99% confidence interval for the true difference in population mean temperatures that adults and children find most comfortable?

4. Two randomized-controlled trials of routine ultrasonography screening during pregnancy were carried out, to see whether routine ultrasound imaging influenced outcomes of pregnancy such as birthweight and mode of delivery. No significant differences were found. At ages 8 to 9 years, 2011 singleton children of the women who had taken part in these trials were followed up. Ultrasonography had actually been carried out on 92% of the ‘screened’ group and 5% of the control group. No significant differences were found...

Two brands of car batteries, both carrying 6-year warranties, were sampled and tested under controlled conditions. Five of each brand failed after the number of months shown. Calculate a) both sample means and b) both sample standard deviations. Decide c) which brand battery lasts longer and d) which brand has the more consistent lifetime. Brand A: 68, 69, 76, 76, 73 Brand B: 61, 69, 68, 67, 61 What are the sample means?A B What are the sample standard deviations?...
