One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Kala has recorded the travel times for samples of fourteen trips via the 10 Freeway and fourteen trips via the 60 Freeway. The following table gives the travel times (in minutes) for the twenty-eight trips.

These freshmen are from three different department. Department of Mathematics and statistics have 150 freshmen. Department of Biology have 250 and Department of Nutrition and Dietetics have 100. a. What sampling technique we will use to choose the 70 students needed on the study? b. Solve the three strata. c. Suppose the researchers decided to down the sample to 50, how many freshmen will be needed now to the Department of Nutrition and Dietetics?arrow_forwardFind an article of your choice which uses proportions, and copy and paste the address of that article in this step. Identify at least one sample proportion within the article (you can list more than one if you like), and state what that sample proportion measures. For example, if you're told that the sample proportion of people in Renton who are taller than 5'11" is 80.7%, and you're also told that the sample size is 57, then you would state the proportion as 46/57 in your response for this part of the assignment. You will probably have to interpret what is being said in the article in order to be able to state specifically what the sample proportion represents. Also, you might not have � or �, you might only have the percentage or a decimal equivalent. Often, the size of the sample is stated somewhere in the article, and it's important to find that value. So, if � is given, please include it in this part of the assignment. If stated in the article, identify whether the sample is a…arrow_forward
