Practice Concluding a Hypothesis Test For each of the scenarios below complete the following: Identify the null and alternative hypothesis. State if the results are statistically significant and why Conclude the hypothesis test in context Notice that the scenarios are similar to the previous worksheet with slight changes. 1. We are interested in answering the question: In Richmond Kentucky, are less than 75% of stray dogs spayedeutered? A random sample of 150 stray dogs found that 70% were spayedeutered. The test was performed at the 10% significance level and the resulting p-value was 0.051. 2. We are interested in answering the question: Is the average price of Pepsi 2-Liter bottles in Kentucky less than 99 cents? A sample of 75 stores selling Pepsi 2-liters found an average price of 96 cents. The test was performed at the 1% significance level and the resulting p-value was 0.0065. 3. A researcher believes that if patients with arthritis go to physical therapy twice a week their pain levels will be lower than usual pain levels. Patients with arthritis usually rate their pain a 3.5 on an 8- point scale. The test was performed at the 10% significance level and the resulting p-value was 0.113. 4. A neonatal nurse suspects that newborn babies are more likely to be boys than girls. A random sample found 13,173 boys were born among 25,468 newborn children. The test was performed at the 2% significance level and the resulting p-value was 0.0132
