R for my statistics class and need to write the code for this problem: "An experiment with four treatments and five replications of each treatment, which requires 20 experimental units. How many randomizations are possible for this experiment?"
Determine the p-value; and at 93.7% confidence, test the above hypotheses.
If none is satisfactory, explain. (e) Make a forecast for 2004 by using a trend model of your choice or a judgment forecast.
The average on an exam is 75 and the standard deviation is 17. If the instructor assigned grades based on the Normal distribution what percentage of students will make A's and what percentage will make B;s in teh exam. Assume standard cut-off for ..

A biology professor claimed that the proportions of grades in his classes are the same. A sample of 100 students showed the following frequencies:
If you were designing a study which group, a population or a sample, would you gather data from and why? Provide an explanation regarding whether or not the standard deviation is a biased or unbiased estimate.

Change the frequencies to percentages - is there a group more likely to get high salaries.
