It is believed that a sweetener called xylitol helps prevent ear infections. In a randomized experiment, 165 children took a placebo and 68 of them got ear infections. Another sample of 159 children took xylitol and 46 of them got ear infections. The scientists believe that the proportion of ear infections in the placebo group will be greater than the xylitol group. Test this hypothesis at α = 0.025.
A Researcher Studying The Relationship Between Maternal Age And Length Of Breastfeeding In A Sample Of 75 Primiparas Found A Correlation Of .19, Which Was Not Statistically Significant At The .05 Level. What Was The Estimated Power Of The Statistical Test?
Conversely, What Was The Risk That A Type II Error Was Committed?
If .19 Is A Good Estimation Of The Population Correlation, What Sample Size Would Be Needed In A Replication Study To Achieve Power = .80 At Α= .05?
Rosner analyzed data from children who lived near a lead smelter (which is a facility that uses extreme heat to extract the metal lead from lead ore) in El Paso, Texas, and reported that out of 124 children studied, 23 developed colic (which is a pattern of fussiness and crying for no apparent reason). Suppose that in the state of Taxes in general at the time (early 1980s), the rate of colic in children was 16.0%.
Follow the steps for testing whether the proportion of children developing clico was significantly different for the 124 children living near the lead smelter than for Taxes children in general (16%).

- A survey claims that 9 out of 10 doctors recommend aspirin for their patients with headaches. To test this claim against the alternative that the actual proportion of doctors who recommend aspirin is less than 0.90, a random sample of 100 doctors results in 83 who indicate that they recommend aspirin.
