A professor conducts an experiment that investigates the effects of a new statistics CD on student understanding. His one statistics class is used for the sample. He divides the roster into two halves and uses each half as a group. One group receives the CD and the other does not receive the CD. Each group consists of 10 students. Observations of student classroom engagement are rated by the professor, according to an engagement scale. How could this study be improved?A. Randomly assign the students to the two different groups.B. Repeat the study again, when a larger sample size can be derived.C. Use an instrument that measures student understanding.D. Ask another professor to make and rate observations, as well.

The picture shows a feeding trough that is shaped like a right prism. (Picture is shown at the bottom!!) Plz, answer these three questions. I have my answers, I just want to double check!(a) Surface A and B are identical trapezoids. What are the lengths of the bases of the trapezoids? What is the height?(b) Surfaces A and B will be painted blue. What is the total area that will be painted blue?(c) The edges of the trapezoids need to be sanded. A piece of sandpaper advertises that it can sand up to 80 cm. Will one piece of sandpaper be enough to sand the edges of one trapezoid? Explain.Brainleist to the first and correct answer!

1. A farmer divided a field into 1-foot by 1-foot sections and tested soil samples from 32 randomly selected sections in the field. He finds that the mean pH level of the samples is 5.7 with a standard deviation of 0.26.A. Find the mean and standard deviation of the sampling distribution of all possible soil samples of size n = 32. Round to three decimal places.B. Construct a 95% confidence interval for the mean pH level of soil samples from every 1-foot by 1-foot section. Show your work. Even if you use technology, show the expression that is used to determine the margin of error for the interval. Interpret the interval in a complete sentence. C. The farmer tested soil samples from 34 randomly selected sections from another field. He found the mean pH level of those samples to be 6.1 with a standard deviation of 0.34. Construct a 95% confidence interval for the difference between the mean pH levels of all possible soil samples from both fields. Show your work.
