A small university was looking to recruit students for their golf program during Freshman orientation. Each organization would be allotted 10 minutes to give a small presentation about their program. The golf coach wants to discuss the programs golf over the past five years during his presentation. To do this, he plans to take samples of the scores from both practice rounds and games. He has recruited students from Statistics class to help him determine which statistic would be best to use to display the scores. The students have narrowed it down to four different statistics. For each statistic, the coach has taken 100 random samples of golf scores over the past five years and the statistic is calculated for each sample. Suppose the value for the population parameter he is trying to estimate is a score of 75. ALL GRAPHS ARE IN THE ATTACHED PICTURE!! THANK YOU!! a) For each graph above, identify whether the statistic appears to have a biased or unbiased estimator of the population…
To investigate whether one-pound bags of potato chips actually contain a full pound of chips, a skeptical statistics student goes to the supermarket and weighs every bag on the shelf. To analyze these data, what statistical test should i use?
A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. Before opening the data, what would you hypothesize about this research question? Open the data set. Before running any statistical analyses, glance through the data. Do you think that your hypothesis will be supported? Conduct descriptive analyses and report them here. Conduct a one-way ANOVA. Report your statistical findings (including any applicable tables in APA format) here. What would you conclude from this analysis? What would be your next steps, if this…

The concept “Job Involvement” is defined as the degree to which an employee is engaged in and enthusiastic about performing his/her work. In a study one section of the questionnaire was designed to measure “Job Involvement” of the employees. There were 6 items in this construct, each measured on a Likert scale of 1 to 5: JINV1. The major satisfaction in my life comes from my job JINV2. My job means a lot more to me than just money JINV3. I will stay overtime to finish a job, even if I am not paid for it JINV4. I look forward to coming to work each day JINV5. I would probably keep working even if I didn’t need the money JINV6. The most important things that happen to me involve my work The questionnaires were self-administered and 200 cases were used in the final analysis. The data were analysed using SPSS. The following are some of the output from factor analysis. 1) Interpret the values presented in the Table 9. 2) Interpret the values presented in Table 10 3) Write a brief…

For effective learning, an instructor advised his students to practice solving statistical problems on StatCrunch, a web-based software, at least 7 hours per week. In an in class activity, a student surveyed 15 of her 35 classmates to assess the number of hours they spend per week practicing statistics on StatCrunch. The following data was collected: 6.5, 4, 3.5, 0, 12, 5, 12, 15, 12, 0, 1, 8, 0.5, 2, 7. Is there strong evidence that the mean number of hours of StatCrunch usage in the entire class is larger than 7? Let the confidence level be 95% Find the mean Standard deviation T / z score Find the critical score Draw the normal curve with critical tscore and test statistic. Make a conclusion

People often say “Distance makes the heart fonder.” Interestingly, due to pandemic related lockdowns, some persons have been implicitly or explicitly indicating that it is indeed true as they have been struggling with their relationships due to lack of time apart from their partner. A researcher who is interested in such an issue decided to collect data on the level of rage/edginess that exist among a few couples due to lockdowns. Participants were asked to rank the level of hostility they think they have been exerting towards their partner due to having to spend more time than they usually do with them. The resulting data is presented on page two (2). 2 *14 is the highest level of hostility. Level of hostility Number of partners 0-1 4 2-3 11 4-5 8 6-7 20 8-9 25 10-11 12 12-13 12 13-14 4 a.

From candy to jewelry to flowers, the average consumer was expected to spend $104.63 for Mother’s Day in 2005, according to a Democrat & Chronicle article. Local merchants thought this average was too high for their area. They contracted an agency to conduct a study. A random sample of 60 consumers was taken at a local shopping mall the Saturday before Mother’s Day and produced the sample mean amount of $94.27. If σ = $29.50, does the sample provide sufficient evidence to support the merchants’ claim at the 0.03 level of significance? 1. Do you recognize any flaws in this study and what conclusions can you draw? The article “Well-fed Crickets Bowl Maidens Over” reports that female field crickets are attracted to males that have high chirp rates and hypothesized that chirp rate is related to nutritional status.
