Calculate the mean and standard deviation for the population. b. Now take 10 samples of size 3 from the population. Use either simple randomsampling or systematic sampling with the help of the table of random numbers inAppendix A. Calculate the mean for each sample.C. Oncehave calculated the mean for each sample, calculate the mean of meansyou(i.e., add up your 10 sample means and divide by 10). How does this mean comparewith the mean for all states?d. How does the value of the standard deviation that you calculated in Exercise 8acompare with the value of the standard error (i.e., the standard deviation of thesampling distribution)?e. Construct two histograms, one for the distribution of values in the population andthe other for the various sample means taken from Exercise 8b. Describe and explainany differencesyouobserve between the two distributions.f. It is important that you have a clear sense of the population that we are working within this exercise. What is the population?

7. Construct a sub-divided bar diagram from the following data, regarding the number of stu- dents in 2 colleges. College Arts Science Соmmerce Agriculture Total A 1,200 800 600 400 3,000 750 500 300 450 2,000
A researcher interested in determining if there is an association between head circumference and brain volume tested for linear correlation at the a= 0.05 significance level. She took a random sample of twenty adults and measured the head circumference and brain volume (using ultrasound) for each person in the sample. The table above gives the paired data for the twenty adults. The researcher determined there is positive linear correlation between head circumference and brain volume at the 0.05 level of significance. With that information answer the following questions. 1.) Since we've determined there is linear correlation between head circumference and brain volume from the output on the TI83/84 what is "a" the y-intercept of the regression line? A. a=.508 B. a=34.740 C. a=-110.572 D. a=-823.829 2. Since we've determined there is linear correlation between head circumference and brain volume from the output on the T183/84 what is "b" the slope of the regression? A. b=34.740 B. b=.508…
On the following pages you are presented with five problems. Your job is to examine the output and discuss whether there is a statistically significant relationship between the two variables, the pattern or direction of the relationship if the relationship is significant, and the strength of the relationship if the relationship is significant. AS you discuss the strength of the relationship, you will rely on an appropriate measure of association from those that have been given. For that determination, you will need to appropriately determine the level of measurement of each of the variables being examined. Please use the Measures of Association Chart I provided to help you with your determination. You may write your responses on a separate document or next to the problems on this one.
