Q1: Final Project Research Title: Investigating the Impact of Smartphone Usage on Sleep Quality and Academic Performance Among the 10 students given in the table below. Significance level (a=0.05). Case Study I: the Impact of Smartphone Usage on Sleep Quality. Case Study II: the Impact of Smartphone Usage on Academic Performance. Calculate the numerical measures (Mean, Standard Deviation, Median, Mode) for each case and perform the same calculations using Excel. Compute the correlation coefficients for each case, both numerically and by employing Excel. Utilize the quantitative methodology to investigate the relationships among the variables, ensuring to identify and include all the components of this research method. Is there a relationship between sleep quality and performance? Please provide the interpretation. Prepare a Research Proposal on the given topic, taking into account all the elements of the attached research proposal.

Q1: A new restaurant would like to investigate if different age groups of customers prefer different types of food items. Each of their customers is given a food item - a burger or a sandwich. Each customer belongs to either adult or child age group. The customers were then surveyed on whether they enjoyed the food item. The table below gives the percentage of customers in each category.See Answer

Create a full adder circuit. 4. Create the lookahead carry unit block defined in the 4-bit carry lookahead adder circuit. (see lecture handout) 5. Create a 4-input odd function circuit. (see lecture handout)See Answer
Q1: 3) A single laser source is to be used in an optical fibre detection network containing 4 different detection channels, each of which is 18km away from the source. This can be achieved using a 1:4 optical fibre splitter, which allows 25% of the power from the laser to pass down each channel. If the fibre has an attenuation coefficient of 0.5dB/km and the required output power is 0.35?W what is the required laser power assuming no joint losses, margin or penalties.See Answer
Q1: Reconsider the three bit synchronous counter register described in the lecture notes. Use the counter symbol to control the lights of a street intersection. Street 1 has lights G1, Y1, R1 and street 2 has lightsG2, Y2, R2. ) Draw a schematic using the counter to make a counter that counts 000 to 101 and overflow back to count 000. There is a clock input and negative logic clear signal clrn. The reset state is 000. b) The following table shows that each light is green for two units of time, yellow for one unit of time, and red for three units of time. The u symbol indicates unused states.See Answer
Q1: 3.) A diaphragm pressure gauge employs four strain gauges to monitor the displacement of the diaphragm. The four active gauges form the arms of a Wheatstone bridge, in the way shown in Fig. 3.23 b (see class notes too). The gauges have a gauge factor of 2.1 and resistance 120 Q. A differential pressure applied to the diaphragm results in two of the gauges on one side of the diaphragm being subject to a tensile strain of 1.0 x 10^-5 and the two on the other side a compressive strain of 1.0 x 10^-5 . The supply voltage for the bridge is 10 V. What will be the voltage output from the bridge? (20 pts) (Answer is 0.21 mV, but you need to show the work to get to this.)See Answer
Q1: Can use MATLAB or Python 1) Implement bit plane coding and design a GUI for real time progressive transmission demonstration. 2) Implement Burt-Adelson's pyramid method using Gaussian windows and design a GUI for real time progressive transmission demonstration. Also give explanation how each of the question is done. Please note that your GUI demonstration must be included as a package so that they can be run on a computer for grade evaluation.See Answer
