Researchers compared the reaction times in people who were sleep deprived versus people who had gotten a full night's rest. The following are typical data showing the reaction time scores (in seconds) for two groups (samples) of participants.

______________________________

Sleep deprived Well Rested

3 5 2 3 7 3 1 2 2 1

6 1 9 2 11 1 2 3 3 5

10 3 3 5 4 2 3 1 3 2

Compute the mean, the range, the variance, and the standard deviation for each group.
Is one group of scores more variable than the other?

Recall the researcher who investigated the relationship between hours of sleep and reaction times in the Week 4 Application. As a follow up to that study, the researcher wants to conduct a correlation to investigate further if there is a relationship between hours of sleep and reaction time. For this experiment, participants are allowed to sleep as much as they would like (that is, they are not assigned to sleep any specific number of hours). When 20 participants come to...

A sleep center hypothesizes that people who sleep only four hours will score lower than people who sleep for eight hours on a cognitive skills test. The center recruited 20 participants and split them into two groups, giving one group 8 hours of sleep and the other only 4 hours. The following morning, the CAT (Cognitive Ability Test) was conducted, with scores ranging from 1-9, 9 being the best score. Use this information to answer questions . CAT Scores Group...

Researchers were interested in whether older parents had different parenting styles when compared to younger parents. Parenting styles were classified into one of three categories: permissive, authoritative or dictatorial. Using the information provided in the tables below, answer the following questions. 1. What are the total number of older parents in this study? 2. What was the expected count and actual count of younger parents who have dictatorial styles? 3. What was the overall sample size? 4. What percent of...

When the chickenpox vaccine was developed older people who had not had chickenpox were among the first to be able to get the vaccine. However, sometimes people have such a minor chickenpox infection that it goes unnoticed, yet still generates complete adaptive immunity. Before giving the vaccine, healthcare workers would test potential recipients to see if they already had chickenpox and had immunity to the virus. Describe how you could develop an ELISA test to determine if someone had immunity...

Question 1: Researchers were interested in the effect of sleep on memory consolidation. Twenty-four participants were randomly assigned to either a “Sleep” or “No-Sleep” group, such that there were 12 participants in each group. On the first day, all participants were flashed pictures of 15 different objects on a computer screen and asked to remember as many objects as possible. That night, the “Sleep” group got an ordinary night’s sleep. The “No-Sleep” group was kept awake until the second night....

The researchers examined the mean age of the patients who were depressed and those who were not. Write an appropriate null and alternative hypothesis. What would be a good statistical test for this analysis and why? The corresponding p value is 0.25? What do you conclude?

During a recent Ebola outbreak, researchers attempted extracting antibodies from people who had been infected but survived. They then injected other people with these antibodies to help them overcome the illness. Even more recently, an experimental vaccine against Ebola has been approved for emergency use in the Democratic Republic of the Congo. Ebola is a virus that infects macrophages and dendritic cells. In doing so, it causes dysregulation in several ways. For example, 1) it prevents infected cells from secreting...

A) Two arthroscopic surgeries were compared among patients suffering from osteoarthritis who had at least moderate knee pain. The lavage type has the joint flushed with fluid and no instrument is used to remove tissue; the debridement type has the joint flushed with fluid and an instrument is used to remove tissue. Knee pain scores, ranging from 0 to 100 with higher scores indicating severe pain, were obtained for patients randomly assigned to the two groups after the surgery and...

Problem 3 You hypothesize that people who drive sports cars have faster reaction times than those who drive nonsports cars (e.g., sedans, pickup trucks, etc.). You design a task that measures response time to detect a visual target presented on a screen for 500 ms. The two types of drivers completed 300 trials of the task and the mean reaction times were calculated. The data are shown on the right. Did you find support for your hypothesis? Use the four-step...
