Show me the steps to solve Fifteen subjects were randomly assigned to one of two groups in a study investigating the effect of distraction (noise) on test-taking performance. 8 subjects in Group 1 took a test under normal conditions, while 7 Group 2 subjects were subjected to intermittent bursts of white noise while taking the same test. The groups' scores are as follows: is there a significant difference between them if all necessary tests are performed with α ≤ .10? The mean score for Group 1 was 77.75 with a standard deviation of 9.13. The mean score for Group 2 was 57.43 with a standard deviation of 19.33

A. A researcher, Dr. Smith, is conducting a study on the academic performance of students at a local high school. The results of this study will provide valuable insights into the academic performance of students at the high school and inform potential interventions to support student success. To investigate the average test scores of students, Dr. Smith randomly selects a sample of 8 students from the population of all students at the school. After collecting the data, Dr. Smith calculates the sample mean test score to be 68, with a standard deviation of 50. Required: Using the 6-step process of hypothesis testing learned in HM6007, assess whether he would be able to conclude with 90% confidence that the population mean is less than 85.

. Derive the current voltage characteristics for the MOSFETs shown below. The top and side views of the MOSFETs are shown. Try to obtain closed form solutions. It is alright if you cannot obtain closed form solutions, but you must explain your approach. (21 marks) (a) Gate oxide thickness varies linearly from source to drain. Channel width varies linearly from source to drain. The parameter $a > 1$. (b) There a -ve ion sheet charge in the dielectric as shown. The ion concentration varies linearly from source to drain. The parameter $a > 1$. (c) A metal which forms a Schottky contact with a p-doped semiconductor is used as the gate metal for a MOSFET based on the same p-doped semiconductor. The insulator is poor and has pin holes resulting in the gate metal contacting the semiconductor. The pin hole density is measured by the ratio of pin hole area to the total area for any region of interest. This density varies linearly from the source to the drain. The parameter $a > 1$.
