Before taking the plunge into videoconferencing, a company ran tests of its current internal computer network. the goal of the tests was to measure how rapidly data moved through the network given the current demand on the network. eighty files ranging in size from 20 to 100 megabytes (mb) were transmitted over the network a various times of day, and the time to send the file (in seconds) was recorded.
1. create a scatterplot of transfer time on file size. does a line seem to be a good summary of the association between the variables?
2. estimate the least squares linear equation for predicting transfer time.
3. interpret the fitted slope and intercept. be sure to include their units.
4. what is the value of the standard error? be sure to include the units.
5. plot the residuals from the regression. does this plot show a pattern? if so, what type of pattern?
6. the goal is to get data transferred in no more than 15 seconds. how much of the data do you think can be transferred in this length of time? how did you estimate this?

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e. g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
