4. I would like to design a randomized experiment in which only 1 factor is being investigated. I am assessing if varying the filtration time affects the volume of filtrate collected after 5 hours. What is random variable being investigated here? A. filtration time B. filtrate C. volume of filtrate D. type of filter paper 5. Which is a proper way of conducting this experiment (#4 problem)? A. Set 3 different volumes of filtrate and measure filtration time of 2 observations each. B. Set 3 different filtration times and measure at least 2 observations of filtrate volume for each. C. Set 2 different filtration times and measure at least 3 observations of filtrate volume for each. D. Set 2 different volumes of filtrate and measure filtration time of 3 observations each.
2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:
← Jamison Kovach Supply Company manufactures paper clips and other office products. Although inexpensive, paper clips have provided the firm with a high margin of profitability. Sample size is 200. Results are given for the last 10 samples. Sample Defectives 1 UCL 5 = 2 7 3 2 4 6 5 6 6 5 b) Has the process been in control? Based on the developed control limits, the number of defectives has been IN-CONTROL c) If the sample size were 100 instead, how would your limits and conclusions change? 7 5 The type of control chart that is best to monitor this process is p-chart a) Establish the control limits to include 99.73% of the random variation in defectives.

You intend to conduct a independence for a contingency table with 6 categories in the column variable and 3 categories in the row variable. You collect data from 102 subjects. What are the degrees of freedom for the x² distribution for this test? d.f. =
A biologist wants to determine if different temperatures (15oC, 25oC, or 35oC) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations. What type of sampling is described in this study? one sample paired data two samples more than two samples

You conduct a one-factor ANOVA with 6 groups and 10 subjects in each group (a balanced design) and obtain F 2.07. Use Excel to find the requested values (report p-value accurate to 4 decimal places). betwee dfwithin p =
To compare the effects of four different chemicals in producing water restance in textiles, a strip of material randomply selected from a bolf of chemical was cut ito four pieces were randomply assigned to receive an application of one of the chemicals A, B, C, or D. Low readings indicate low moisture penetration. Refer to the table below. Is there a significant difference among the four chemicals? State the null hypothesis. Bolt Samples 2 3 Chemical 10.1 12.2 11.9 A Chemical 11.4 12.9 12.7 В Chemical 9.9 12.3 11.4 C Chemical 12.1 13.4 12.9 O a. There is no significant difference among the four chemicals. O b There is a significant difference among the four chemicals.
Imagine a researcher asks a sample of five people to drive two types of cars and rate each of them on a scale of 1 to 25. The researcher wants to know: Is there is a difference in the ratings of the two types of cars. Below are the data collected: Type A: 20, 10, 11, 23, 7 Type B: 10, 11, 4, 12, 1 What type of analysis would be appropriate to address the researcher’s question and why did you make this choice? Conduct the analysis identified in “1” above using jamovi. Use α = .05. Is the assumption(s) met? What do you conclude? Present your answer in APA. ** NB I asked these already using the responses please help answer question 2 2 Based on your decision in the questions above identify and explain the type of error you could be making
is described below. NOTE: If the method is experimental, indicate if it is a true experiment or quasi experiment. 1. I get 30 people and use random assignment to divide the people into two groups. One group reads an article about the statistics of injuries and deaths caused by people using smart phones while driving, the other group watches a short video about a person who killed someone while using their smart phone. Both groups are then monitored to see if either of these made a difference in how often these people use their smart phones use while behind the wheel. What method would that study be? 2. What method asks a series of questions that are all planned in advance?
A survey will be conducted to compare the grade point averages of US high-school students from four different school districts. Students are to be randomly selected from each of the four districts and their grade point averages recorded. The ANOVA model most likely to fit this situation is: O oneway ANOVA based on independent samples. O two-way ANOVA based on independent samples. O one-way ANOVA based on randomised blocks. O random effects ANOVA
