I use the ANOVA table but had a hard time with some of them. To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained thefollowing data on the time (in minutes) needed to mix the material.Manufacturer123213320273119253623233222a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05.Compute the values below (to 2 decimals, if necessary).Sum of Squares, TreatmentSum of Squares, ErrorMean Squares, Treatment

You may need to use the appropriate technology to answer this question. It is reported that the time married men with children spend on child care averages 6.5 hours per week. You belong to a professional group on family practices that would like to do its own study to determine if the time married men in your area spend on child care per week differs from the reported mean of 6.5 hours per week. A sample of 40 married couples will be used with the data collected showing the hours per week the husband spends on child care.

If a researcher wants to test the claim that the proportion of job seekers turned downed for a job is the same for Caucasians, Blacks, Hispanics, and Asians, then the researcher can use a 1-way ANOVA. O true O false
You are a medical researcher that wants to determine if your new drug can lower people's blood pressure. You recruit 60 participants with high blood pressure to be part of your study. You randomly assign participants to one of three groups to receive either 10 mg of your drug, 5 mg, or 0 mg (given as a placebo control). After 2 weeks, participants' blood pressure is measured and you compare among the 3 groups. Which statistical test would be best to determine if there is a significant difference in blood pressure among the three groups? one-sample t-test related samples t-test independent samples t-test ANOVA
For a two-way ANOVA, define the following concepts: a. levels of Factor B b. no interaction c. a main effect due to Factor A

Please help with question 3. Thank you
Please see below. I really need help with these. I am only given one attempt at these so please be certain of your work. Refer to the following scenario. True or false scenarios. An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 336 people living in East Vancouver and finds that 38 have recently had the flu. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of East Vancouver residents who have recently had the flu(THESE ARE TRUE OR FALSE). A. 11.31% (38/336) of East Vancouver residents have recently had the flu. B. There is a 95% probability that the true proportion of East Vancouver residents who have recently had the flu equals 38/336. C. If another…

For a two-way ANOVA, suppose that Factor A has four levels and Factor B has three levels, and that there are five observations for each treatment combination. Given that SSA = 1200, SSB = 800, SSAB = 240, and SSE = 144, construct the two-way ANOVA table for the data.
Students often confuse the concepts of Random Sampling and Random Assignment (probably because they both contain the same word "random"), but these are different tools designed to solve different problems. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as the research problems they are used to solve.
The drug manufacturer claim that taking gemfibrozil is beneficial to reduce the chance of heart attacks. 2051 men took the medication, and a control group of 2030 men took a placebo. During the next five years, 56 men in the drug group and 84 men in the placebo group had heart attacks. We would like to compare the proportion of men who develop heart attacks between the drug group and the placebo group. What are the correct x1 and x2 values in order to calculate the pooled sample proportion? a) x1=2051, x2=2030 b) x1=2051, x2=84 c) x1=56, x2=2030 O d) x1=56, x2=84
