Does advertising influence children as young as three? Researchers at Stanford University conducted a taste test with preschoolers. Each preschooler tasted two identical samples of five food items (hamburger, french fries, chicken nuggets, baby carrots, and apple slices). For each item, the children tasted one sample wrapped in a McDonald's wrapper and the other sample in an identical, but unbranded, wrapper. Some children tasted the sample in the branded wrapper first, others tasted the sample in the unbranded wrapper first. Consistently for all food items, the majority of preschoolers preferred the food in the McDonald's wrapper over the one in the unbranded wrapper, even though both samples were identical. [Source: Robinson, T. N., et al. "Effects of fast food branding on young children's taste preferences." Archives of Pediatrics & Adolescent Medicine 161 C2007): 792–797]. The researchers found that the preschoolers who watched more television or ate more often at McDonald's were…

3. Bayesian Inference A cab was involved at night in a hit and run accident. In this town there are only two cab companies, the Blue with 80% of the cabs and the Green company with the remaining 20%. As it happened there was a witness to the accident who identified the hit and run cab as Blue. The case came to trial. An important part of the testimony was a test of the reliability of the eyewitness to identify a cab as being either Blue or Green under the same circumstances as those that existed the night of the accident. The result of these tests was that the witness correctly identified a blue cab as blue 70% of the time and a green cab as green 80% of the time. On the basis of the claim of the eyewitness and the test conducted by the court, what is the probability that the cab involved in the accident was in fact Blue as the witness had claimed?

1. Medical personnel are required to report suspected cases of child abuse. Because some diseases have symptoms that mimic those of child abuse, doctors who see a child with these symptoms must decide between two competing hypotheses: H0 : Symptoms are due to child abuse HA : Symptoms are not due to child abuse During an interview, an Atlanta doctor stated, “If it’s actually a disease, the worst you have is an angry family. If it is abuse, the kids in the family are in deadly danger.” What is a Type II error in the context of this problem? Group of answer choices a. A Type II error indicates the doctor rejected Ho, and the doctor is claiming the symptoms are due to child abuse but they actually are not due to child abuse. The family is very angry at the doctor but the kids are not in danger. b. A Type II error indicates doctor failed to reject Ho, and the doctor is claiming the symptoms are NOT due to child…
