The State Transportation Department is thinking of changing its speed limit signs. It is considering two new options in addition to the existing sign design. At question is whether the three sign designs will producethe same mean speed. To test this, the department has conducted a limited test in which a stretch of roadway was selected. With the original signs up, a random sample of 30 cars was selected and the speedswere measured. Then, on different days, the two new designs were installed, 30 cars each day were sampled, and their speeds were recorded. Suppose that the following summary statistics were computedbased on the data.X₁ = 62.1X₂ = 58.94X3 = 71.2SST = 6016Based on these sample results and significance level equal to 0.05, what is the sum of squares between?

The given values are x¯1=62.1,x¯2=58.94,x¯3=71.2.

Answered: Based on these sample results and…

The research scenario states: decide to look at whether there is a difference between the average temperature in the period between 1951-1980 and the average temperature in the period between 1981-2017. Considering that we are interested in the difference.. wouldn't a one-sample t-test be most appropriate?

The accompanying data set includes volumes (ounces) of a sample of cans of regular Coke. The summary statistics are n=36, x=12.192 oz, s=0.096 oz. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that cans of Coke have a mean volume of 12.00 ounces.

The least-squares regression equation is y=761.7x+13,208 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7483. Predict the median income of a region in which 20% of adults 25 years and older have at least a bachelor's degree.
