A health psychologist was interested in the effects of vitamin supplements on the immune system. Three groups of adults were exposed (in a highly ethical way) to the cold virus; one group took no supplements for a week before exposure, another had vitamin C supplements, and a third had multivitamins (excluding C). The severity of the cold was measured as a percentage (0% = not contracted, 100% = very severe symptoms). The psychologist also measured the number of cigarettes that each person smoked per day, as smoking suppresses the immune system. The psychologist was interested in the differences in the severity of the illnesses across different vitamin groups accounting for cigarette usage. What technique should be used to analyse these data?

It is often useful for retailers to determine why their potential customers chose to visit their store. Possible reasons include advertising, advice from a friend, or previous experience. To determine the effect of full-page advertisements in the local newspaper, the owner of an electronic-equipment store asked randomly selected people who visited the store whether they had seen the ad. He also determined whether the customers had bought anything, and if so, how much they spent. Among the respondents who saw the ad, 49 made an average purchase of $97.38 with a variance of $622. Among the respondents who did not see the ad, 21 made an average purchase of $92.01 with a variance of $283.3. Can the owner conclude that customers who see the ad spend more than those who do not see the ad (among those who make a purchase) at 5% significance level?

Need help with this problem. It is believed that large doses of acetaminophen (the activeingredient in over the counter pain relievers like Tylenol) may cause damage to the liver. A researcherwants to conduct a study to estimate the proportion of acetaminophen users who have liver damage. Forparticipating in this study, he will pay each subject $20 and provide a free medical consultation if the patienthas liver damage.(a) If he wants to limit the margin of error of his 98% confidence interval to 2%, what is the minimumamount of money he needs to set aside to pay his subjects?(b) The amount you calculated in part (a) is substantially over his budget so he decides to use fewer subjects.How will this affect the width of his confidence interval?

An educational psychologist is comparing two instructional approaches. She teaches people using visual aids for Approach A, and uses verbal materials for Approach B, and then gives a test after using each approach. The same individuals were used as students of both instructional approaches. She thinks people learn differently when they have visual aids than verbal materials. Approach A:Mean: 26.0 Std. Dev: 8.5 N: 16 Approach B:Mean: 27.0 std. dev: 10.0 N = 16 Difference A-B:mean : -1.0 Std. Dev: 14.0 N = 16 A). What is the type of test you will use? (z-test, single-sample t-test, paired-samples t-test, or independent samples t-test) and why (what information provided in the problem) B). What are the hypotheses (Be Specific)
A report summarizing scores for students on a verbal aptitude test x and a math aptitude test y gives the following results: x = 480, sx = 80, y = 500, sy = 120, r = 0.6.
A clinical psychologist is interested in the effect of a new treatment for treating depression. She randomly divides her clients into two groups. One group receives the new treatment and the other group receives the old treatment (control group). At the end of treatment, she assesses the severity of their depression on a scale ranging from 0 to 20 (higher scores indicate greater depression). Was there a significant difference in depression scores between the two treatments? New Treatment Old Treatment 2 7 5 10 3 6 8 8 11 4 4 8 6 10 4 4
Researchers were interested in how much time balance (i.e., the degree to which you have enough time to do what you like) is related to happiness. They asked 12 adults to answer two questions (on 1 – 8 scales): (a) in a typical week, how much of your time are you able to spend doing the kinds of things that you enjoy (with higher scores indicating more time balance) and (b) taking all things together, how happy would you say you are (with higher scores indicating more happiness)? The research hypothesis is that there is an association between time balance and happiness. Use the Table of Descriptive statistics, correlation (r), the standard error of the correlation (SEr), and the r to zr Table, to go through the steps to compute the 95% CI. Report all values (excluding critical values) to TWO decimal places.Report critical values to THREE decimal places. Compute the following: Report all values to TWO decimal places.The Pearson Correlation = Answer Standard Error (SEr) = Answertobs =…

A researcher is interested in investigating the relationship between sugar consumption and weight gain for high school students. 15 volunteers were randomly assigned to one of two groups. The first group contained 6 volunteers who were put on a low sugar diet. The second group consisting of the remaining 9 volunteers was put on a diet with sugar constituting approximately 15% of their diet. After 8 weeks, the change in weight was recorded for each of the volunteers. Question: What is the response variable? What study principle was used in this study and what kind of study is this?

A psychologist would like to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n=5 in each sample. One group gets no drug, one group gets s small dose, and the third group gets a large dose. The psychologist records the activity level for each animal. The data from this experiment are presented below. No drug Small dose Large dose 5, 3 , 1 , 1 , 5 5, 5, 9, 6, 5 10, 12, 9, 6, 8 =3, SS=16 =6, SS=12 =9, SS=20 Do these data indicate any significant differences among the three groups? Test with α=0.05. Compute the effect size and interpret the result.
A U.S. magazine, Consumer Reports, carried out a survey of the calorie and sodium content of a number of diﬀerent brands of hotdog. There were two types of hotdog: beef, ’meat‘ (mainly pork and beef but can contain up to 15% poultry) and poultry. The results below are the calorie content of the diﬀerent brands of beef and poultry hotdogs. Beef hotdogs: 186,181,176,149,184,190,158,139,175,148,152,111,141,153,190,157,131,149,135,132 Poultry hotdogs: 129,132,102,106,94,102,87,99,170,113,135,142,86,143,152,146,144 Using six steps of hypothesis testing, determine if there is a strong evidence that the calorie content of poultry hotdogs is lower than the calorie content of beef hotdogs.
