Looking for help with the MATLAB code for these questions. Evaluate the line integral (x-3y²) ds where C is the straight line segment from (0, 1, 1) to (3,-2,2), and assign the result to q3.. A piece of wire is in the shape of the circle x² + y² = 1. The density at any point is given by f(x, y) = x² + 14. Find the mass of the wire using a line integraland assign the result to q4.Evaluate the line integral z dx + xyz dy + xy dz where C is the top half of y²+2² = 4 in the plane x = 2 traveling from left to right (negative y to positive y). Assign the resul to a5.

1. Evaluate the integral from 0 to 2 of (3 - x) dx:% Define the function for the integrand f = @(x)…

Answered: Evaluate the line integral (x-3y²) ds…

When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep n =14 n = 14 M = 72 M =65 SS = 932 SS = 706 Will the 6-hour sleep show a much higher performance rate? This time use a one-tail with alpha = .05 Show all of the steps. Remember use the attached t-distribution chart when obtaining your…

A parent downloads an app that allows him to monitor the amount of screen time his child is using on the phone. The child claims that she is only using 1 hour per day on the phone on average, but the app, over the course of 47 days, finds that the child used an average of 1.2 hours per day. The parent wants to know if the child is using an average of 1 hour per day for all days of use. a) The 1.2 is a/an: variable population parameter sample statistic observational unit b) The sample size is: 1 47 1.2 c) Each day is a/an: population parameter observational unit variable sample statistic
A researcher is interested in the effect of listening to music on knowledge acquisition. She randomly selects 82 students from her Introduction to Psychology course to participate. Half of the selected students is asked to listen to music of their choice while studying for an exam and the other half is asked not to listen to any music while studying. After the exam, she computes the exam scores and obtains results presented below. Can the researcher conclude that there is an effect of listening to music on knowledge acquisition? Conduct the appropriate statistical test (two-tailed) with a = .05. Music group (m) O dependent samples t test one sample t test independent samples t test X 97.3 m S = 9.0 m Based on the information provided above, which statistical test seems most appropriate? z test No music group (nm) X = 93.1 nm S nm = 10.0

I want a manual solution, I would appreciate it if you could send the matlab code as well.
Hello, can you please help me with at least items F and G? I hope it's also explained well and has calculations if there are. I hope you don't do it in image form for easy copy. NOTE: xxxxxCan you also not do it like this one: P(all three have disease)===≈P(D1∩D2∩D3)P(D1)·P(D2)·P(D3)(0.049)·(0.023)·(0.078)0.000088 :) :) :) Instead do it more simple like this: : c)The probability that none of the three people have Alzheimer's =(1−0.049)*(1−0.023)*(1−0.078)=0.856655=(1-0.049)*(1-0.023)*(1-0.078)=0.856655 The probability that at least one of the individual have Alzheimer's =1−P(none of them have Alzheimers)=1−0.856655=0.143345
