In an optical ﬁbre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0.35 W, how far will a signal be transmitted before the power is attenuated to 350 μW? As part of your answer, include a table showing the signal power (in W) vs. distance in 30 km intervals (like Table 1.2 in Section 1.4.4). If a high-quality coaxial cable (LDF5-50A) operating at 200 Mbps is used instead of an optical fibre, how would you expect the calculated distance value to change? Briefly explain your answer (see Section 1.4.4). You are not required to include another table.
The Transform 66 Outside the Beltway project, scheduled to be completed late 2022, is an expansion of the current highway that will provide new travel choices for drivers and hopefully congestion relief from the Capital Beltway (I-495) to Gainesville for a 22.5 mile stretch. This 22.5 mile stretch of I-66 will go through both Fairfax County and Prince William County. VDOT had team members from the project reach out through a phone survey for a random selection of 3,500 residents from both Fairfax County and Prince William County. One question asked on the survey was “Do you feel that the new I-66 Express Lanes will bring congestion relief?” Of the Fairfax County residents surveyed, 1,642 agreed they thought that the expansion will bring congestion relief while only 1,576 of the Prince William County residents surveyed agreed with the statement. 1) What is a possible confounding variable that might have introduced sampling bias intothe results of the survey? Answer in one to two…

People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives. Those who have what is known as “secure” attachments are comfortable with their partners emotions, can help soothe, and make movements towards the other person in a responsive way. Among a group of 10 individuals rated as having a secure attachment style, a researcher wanted to know if, as they were first being acquainted with another person, the amount of self-disclosure made them like their person more. The data is listed in Table 6 below. Test the hypothesis at an alpha of 0.05 (where increasing scores mean higher disclosure and higher liking). If you knew the new person you are about to go on a date with had a self-disclosure rating of 4, what would you predict your likeability score would be (provide the full regression formula as well as the response)? -use…
