trying to determine if there is a significant difference in the mean approval based on education level. The accompanying approval data comes from a samp ditionally, you will find a partially completed ANOVA table, complete the table, use it to address the following questions. se a significance level of 0.01.

Need helop with this question. Thank you :)

Available below are amounts of arsenic in samples of brown rice from three different regions. The amounts are in micrograms of arsenic and all samples have the same serving size. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different​ regions? Given that the amounts of arsenic in the samples from region C have the highest​ mean, can we conclude that brown rice from region C poses the greatest health​ problem?     view the data table of the arsenic amounts.   Arsenic Amounts (micrograms)                             A 4.9 4.9 4.9 5.2 5.3 5.5 5.6 5.7 5.8 5.9 6.1 6.3   B 2.3 3.6 4.5 4.6 4.8 4.8 4.8 5.1 5.1 5.4 5.4 5.5   C 5.7 5.7 6.7 6.9 7.1 7.2 7.2 7.3 7.3 7.4 7.5 7.6               What are the hypotheses to​ test?   H0​: mu 1 equals mu 2 equals mu 3μ1=μ2=μ3   H1​: At least one…

Scores in the first and final rounds for a sample of 20 golfers who competed in tournaments are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. Due to a recent change by Microsoft you will need to open the XLMiner Analysis ToolPak add-in manually from the home ribbon. Screenshot of ToolPak X Open spreadsheet Suppose you would like to determine if the mean score for the first round of an event is significantly different than the mean score for the final round. Does the pressure of playing in the final round cause scores to go up? Or does the increased player concentration cause scores to come down? a. Use a = .10 to test for a statistically significantly difference between the population means for first- and final-round scores. What is the p-value? p-value is What is your conclusion? There is no Final round (to 4 decimals) b. What is the point estimate of the difference between the two population means? (to 2 decimals) For which round…
