23 views A well-known multinational FMCG produces more than fifty products and sells them in the market. Out of fifty products one is mineral water for drinking purpose and supplies different size pack bottles in the market. Product manager observed that, during hot days the sale of water is more as compared to the normal days. He started the collection of data of weekly sale of water and the average weekly temperature.

A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

↑ The 1990 census reported that 32% of the households in Middletown were homeowners and the remainder were renters. During the next decade, 10% of the homeowners became rent and the rest continued to be homeowners. Similarly, 14% of the renters became homeowners and the rest continued to rent (A) Fill in the appropriate transition matrix for this process. Homeowners Homeowners Renters Renters AR NE
Determine whether each situation/question would best be determined by an experiment or a survey/study. 1. [ Select ] Andre wants to estimate the percentage of teenagers who wear glasses v. the percentage that are supposed to wear them and don't. He randomly selects 50 students from his school. 2. [ Select ] Lorain wants to know if eating a small serving of dark chocolate before taking a test has any effect on the grade earned for that test.

A researcher wants to see if gender and/or income affect 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 - affect 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 affected total help if he rejects the null hypothesis. Is there significance for either gender or income?
Digital self-service or Self Service Technology (SST) cannot be neglected in the modern world. Hotels are also adopting self-service technology where check-in and check-out kiosks makes guests' arrivals more pleasant and less turbulent. Knowing this, Anna has decided to choose the "self-service technology in hotels" as title for her Master's project paper. Anna wants to find out how satisfied hotel guests are with the self-service technology. Anna talked to a few hotel managers about this title. Managers told her to include variables like satisfaction with SST (i.e. check-in and check-out kiosks), overall satisfaction with the hotel and revisit intention. Since literature review is too time consuming, she decided to go ahead with data collection without reading any articles. She then created a few questions on her own and complete questionnaire development within two days. She then went to five hotels in Kuala Lumpur, and managed to collect 200 completed questionnaires from hotel…
