oscar wants to estimate the proportion of bilingual children in spain. It has been claimed that the proportion is 0.08 but oscar wants to conduct a hypothesis test to show that the ratio is higher than that. She picks 200 children at the from 6 to 10 at random from the regid stry and investigates whether they are age bilingual or not. Out of these 200 children, 23 were in fact bilingual. What is the test statistic that oscar uses in her hypothesis test? 1. 0.91 2. 1.55 3. 1.82 4. 5.99 5. R-command:

In a survey, 37% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 210 pet owners and discovered that 74 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α=0.1 level of significance.
