- Set up a free RStudio account at posit.cloud. At the start of your R session, you should enter the following commands. set.seed(1) e<-rnorm(n = 100,mean = 0,sd = 80) x<-seq(1,100,1) y<-10+15*x + e Follow the examples in the Panopto Videos to use R to obtain the values requested below. (As always, if you round your answers, make sure you do so correctly and keep at least three decimal places.) (a) The smallest value of y = (b) The largest value of y = (c) The standard deviation of y = (d) The mean of y = (e) The median of y = (f) The correlation between x and y = : (g) Using the variable e as data, the p-value for a test of Hoμ = 0 vs. HA μ0 isarrow_forward3. (i) Using the definition of the line integral of a vector field, calculate the line integral L³ F.dy of the vector field F: R² → R² given by F(x, y) = (y, x), and where the curve & is the unit semi-circle centred at the origin, located in the upper half-plane and oriented in the anticlockwise direction. Hint. Represent the curve y as the join of two curves y = 71 + 1/2 (see Example 8.9 in the Notes). [20 Marks] (ii) Calculate the same integral using Green's Theorem. [10 Marks]arrow_forward1. Evaluate the integral ↓ f(x, y)dxdy, of function f R² →R over the domain DC R2, where: f(x, y) = 2x + y and D is the is the triangle with vertices (0, -1), (1,0) and (0,2). Hint. Represent D in the form D = {(x, y) = R² : x = (a, b), g(x) < y < h(x)} for some aarrow_forward2. (i) Describe with a sketch the trace of the following curve in R² (t) = (t² sin(t), t2 cos(t)), (€ -2,2]). [15 Marks] (ii) Find the length of this curve. [25 Marks]arrow_forwardDoes Chi-squared(alpha) always represent the right tail of the the chi-square distribution and does Chi-squared(1-alpha) always represent the left tail of the the chi-square distribution. Also, for a standard normal distribution would Z(1-alpha) be equivalent to -Zalpha in represneting the left tail of the standard normal distribution curve because they both have the same z-score. Furthermore, is my understanding correct in the sense that if we have a critical value,say Zalpha, would the area to the right of it will be alpha and to the left of it would be 1-alphaarrow_forwardmay you please check my answer, and please dont use AI! may thanks, samarrow_forward4-5.5 A manufacturer of capacitors claims the breakdown voltage has a mean value of at least 1 00 V. A test of nine capacitors yielded breakdown voltages of 97, 1 04, 95, 98, 1 06, 92, 1 1 0, 1 03, and 93 V. a) Find the sample mean. b) Find the sample variance using an unbiased estimate. c) Is the manufacturer's claim valid if a confidence level of 95% is employed?arrow_forwardCourse Name: Calculus with Analytical Geometry-1 Course Code: MATH 132 Do not use Artificial Intelligent Apps Instruction: 1.
