A new cold medication claims that, on average, individuals who take the medication recover within 5 days. Dr. Nelson believes the recovery time is longer. She surveys 31 people with colds who take the medication. She finds that their recovery time, in days, is as follows: 7, 5, 4, 8, 5, 5, 4, 4, 5, 5, 6, 4, 4, 5, 4, 7, 5, 7, 4, 6, 4, 3, 5, 7, 8, 4, 7, 4, 6, 4, 6 Perform a hypothesis test using a 9% level of significance. Step 1: State the null and alternative hypotheses. Ho: pV (So we will be performing a right-tailed test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are t-distributed with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P(& v ) = P(tv 2v p-value = %3D Step 4: Make a Conclusion About the null hypothesis. Since the p-value = = a, we do not reject the null %3D hypothesis. We cannot reject the claim that, on average, individuals who take the medication recover

Page 160 #17 We predict that children exhibit more aggressive act after watching a violent television show. The scores for ten children were recorded before they watched a violent show and then after they watched a violent show. Aggression was measured in terms of number of aggressive acts (e.g. hitting, yelling, kicking etc). Sample 1 (after TV show): 5,6,4,4,7,3,2,1,4,1 Sample 2 (before TV show): 4,6,3,2,4,1,0,0,5,2 Is this a one-tailed or two-tailed test?

The National Hurricane Center provides data that list the number of large (category 3, 4, or 5) hurricanes that have struck the United States, by decade, from 1851-2020. Is there sufficient evidence that the number of large hurricanes have remained constant (per decade)? What are the degrees of freedom?

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week. Age Activity 7 4.3 9 3.2 10 1 13 1.5 12 1.2 15 0.8 9 3 12 4 15 1.5 14 1.9 Using excel, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot. Using excel, obtain the simple linear regression linear regression line predicting activity from age. Interpret the intercept and slope of the regression line. By hand, predict the amount of activity for age = 14. By hand, calculate the residual for age = 14 Using excel output, test the null hypothesis that the slope coefficient is zero using the p-value approach. Write one sentence interpreting the meaning of this result. Make sure to report the test statistic…
