Problem 1: Confidence Interval for Percentage of B’s. The data set “STAT 250 Final Exam Scores” contains a random sample of 269 STAT 250 students’ final exam scores (maximum of 80) collected over the past two years. Answer the following questions using this data set. a) What proportion of students in our sample earned B’s on the final exam? A letter grade of B is obtained with a score of between 64 and 71 inclusive. Hint: You can do this...

Project 1 Due Date Problem Knight's Tour: The Knights Tour is a mathematical problem involving a knight on a chessboard. The knight is placed on the empty board and, moving acording to the rules of chess, must visit each square once. 06-JUN-2018 There are several billion solutions to the problem, of which about 122,000,000 have the knight finishing on the same square on which it begins. When this occurs the tour is said to be closed. Your assignment is to...

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...

Question 1: Compute the linear regression
equation (coefficients) between the “year” variable and the
“temperature” variable. In other words, the dependent variable will
be the temperature and the independent variable will be “year”
variable. Write down the equation, the correlation coefficient
R and the standard error.
Question 2.
a. Has the annual temperature trend given by
the regression line increased or decreased? Hint: Which of the
regression line coefficients expresses whether the linear
relationship between temperature and time (in years)...
