A market research firm used a sample of individuals to rate the purchase potential of a particular product before and afterthe individuals saw a new television commercial about the product. The purchase potential ratings were based on a 0 to 10scale, with higher values indicating a higher purchase potential. The null hypothesis stated that the mean rating "after"would be less than or equal to the mean rating "before." Rejection of this hypothesis would show that the commercialimproved the mean purchase potential rating. Use a = 0.05 and the following data to test the hypothesis and comment onthe value of the commercial.Purchase RatingIndividualAfterBefore65637.443398.77.8State the null and alternative hypotheses. se u = mean rating after - mean rating before.)O Ho: Hd>0O Ho: Hd =0O Ho: Hd s0Ha Hd> 0O Ho: Hd soH Hd=D0Ha Hd =D00 + Prl :H OCalculate the value of the test statistic.

The authors of a paper classified characters who were depicted smoking in movies released between a certain range of years. The smoking characters were classified according to sex and whether the character type was positive, negative, or neutral. The resulting data are summarized in the accompanying table. Assume that it is reasonable to consider this sample of smoking movie characters as representative of smoking movie characters. Do the data provide evidence of an association between sex and character type for movie characters who smoke? Use a = 0.05.

The researchers reported: Consumer masculinity was strongly correlated with appearance-related self-esteem (r = 0.40, p < .001) and media influence (r = 0.62, p < .001), but not correlated with overall self-esteem (r = 0.08, p > .05). a. State the correlations that were significant. b. Which correlation was the strongest?
Social functioning is the ability for an individual to interact or adapt in a normal or usual way in social environments. Albert et al. (2007) asked if relatives of patients with OCD are as healthy as those in general healthy populations. They measured the social functioning of relatives using a 36-item survey with scores ranging from 0 (worst possible health) to 100 (best possible health). The mean score for the general healthy population was 77.43. Using the sample data, test whether there was a difference. Scores: 20, 60, 48, 92, 50, 82, 48, 90, 30, 68, 43, 54, 60, 62, 94, 67, 63, 85 State hypotheses 2. Set the criteria using α= 0.05 3. Calculate t 4. What should you conclude?
Lynn University wants to examine whether students display better academic performance in class versus online. They have collected GPAs of two different samples of students, a sample from classes that take place in-person and a sample from classes that take place online. The data set is below.

Are very young infants more likely to imitate actions that are modeled by a person or simulated by an object? This question was the basis of a research study. One action examined was mouth opening. This action was modeled repeatedly by either a person or a doll, and the number of times that the infant imitated the behavior was recorded. Twenty-seven infants participated, with 12 exposed to a human model and 15 exposed to the doll. Summary values are shown below. Person Model Doll Model x 5.11 3.47 s 1.60 1.30 Is there sufficient evidence to conclude that the mean number of imitations is higher for infants who watch a human model than for infants who watch a doll? Test the relevant hypotheses using a 0.01 significance level. (Use ?Person − ?Doll.) Find the test statistic. (Round your answer to two decimal places.) t = Find the df. (Round your answer down to the nearest whole number.) df = Use technology to find the P-value. (Round your answer to four decimal places.)…
Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…

The variable TeamEngagement is a scale score (0 to 20) of how engaged an employee is with the team of colleagues they regularly work with, with higher values representing greater employee engagement with their team. Previous research indicates that Australian public service employees have an average ‘team engagement’ score of 14.5. However, an organisational psychologist at the institute has claimed that this has decreased due to changes made by the current government. Conduct an appropriate test using the TeamEngagement variable to test this claim. NO WRITTEN ANSWERS PLEASE

(b) The team at the Natural-Life company goes out to the city to sell daily. John is a member of the team. He claims that on average, he sells $50,000 worth of their product to each store that he visits per week. The new manager is wary of this claim and believes he may be overstating his sales. To test the claim, the manager took a random sample of 27 stores that the sales representative usually visits weekly and found that the mean amount earned was $48,950 with a standard deviation of $1,250. At the 0.01 level of significance, can it be concluded that John is overestimated his sales? … (ie. his sales might be less than he claimed)
Use the following information to answer the question. Many couples believe that it is getting too expensive to host an "average" wedding in the United States. According to the website www.costofwedding.com,theaveragecostofaweddingintheU.S.in 2009 was $24,066. Recently, in a random sample of 40 weddings in the U.S. it was found that the average cost of a wedding was $23,224, with a standard deviation of $2,903. On the basis of this, a 9 5% confidence interval for the mean cost of weddings in the U.S. is $22,296 to $24,152. Does the confidence interval provide evidence that the mean cost of a wedding has decreased? Explain your reasoning.
