As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a group tested a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVs). Suppose the following data show the miles-per-gallon rating obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVs, and …

As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a group tested a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVs). Suppose the following data show the miles-per-gallon rating obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVs, and two hybrid midsize SUVs; also shown are the miles per gallon obtained for eight similarly equipped conventional models.

EXPERT ANSWER Let us make the grid for the Route cipher and enter the key letters. The grid of 5 row x 4 column is incorrect as it produces this. As mentioned, the message is likely to be encrypted by writing down the plaintext down the columns from right to left and then spiraling counter …

Your job is to decrypt the intercepted message CONTNHRBDWMNACONVJC, which is believed to reveal the location of an important item. Your hint is that it is encrypted using a Caesar cipher, but we do not know the key. However, you have intercepted another message that may provide some useful information. 1. Since we know that the recipient of a ciphertext message must know the encryption key to decode the message, we were looking for a second message containing the key to our ciphertext, and we may have found it. We intercepted the encrypted message NEXYIYECEHTIRISNEHPK. Via social engineering, we believe the message sender likes to use route ciphers in a five-row by four-column grid. Past efforts lead us to believe she prefers to encrypt the message by writing the plaintext down the columns from right to left, and then spiraling counter-clockwise from the top-left corner. If the plaintext doesn’t fill the grid, she often uses X and Y to fill in the spaces. Reverse her process to reveal the plaintext! 2. If you correctly decrypted the message from step 1, you now have the encryption key for the original ciphertext, CQNTNHRBDWMNACONVJC. Use this key and your knowledge of Caesar ciphers to decrypt the first message and find the location of the secret object Read More »

EXPERT ANSWER Answers: Transform the data so a linear trend will fit Look for a different model form, e.g., exponential, polynomial, etc. Explanation: For the given scenario, we cannot fit a linear trend because the scatter plot for the given two variables shows that there is not a linear relationship exists between given two variables. …

An economist is interested in the relationship between the disposable income of a family and the amount of money spent annually on food. For a preliminary study, the economist takes a random sample of eight middle-income families of the same size father, mother, and two children). The results are as follows, where x denotes disposable income in thousands of taka and y denotes food expenditure in hundreds of taka. x 30 36 27 20 16 24 19 25 y 55 60 42 40 37 26 39 43 a. Draw a scatter diagram between x and y. b. Determine and interpret the value of r. c. Determine the regression equation for the data. d.Graph the regression equation and the data points. e.
