Goodness of Fit Test: The distribution of the colors in any bag of regular skittles should be approximately uniformly distributed. There are 5 flavors/colors in a regular mix bag of skittles; yellow, orange, green, purple, and red.g. Many experiments have been done to count the number of skittles in each color from avariety of package sizes. One of which is:Yellow Orange Green Purple Red575. 602 590 610 588h.

I am trying to evaluate an exponential function f(x) = ex. So I tried it first with e2, so I entered e^2 and MATLAB errored. I tried to put parenthesis. It still errored. What seems to be the problem? The answer cannot be found on the other choices. "Sir, exponential function ex are represented in MATLAB as the command exp(x)." "Sir, the syntax is wrong. The e in exponential functions for MATLAB serve as a suffix just like i and j." "Sir, the syntax is wrong. Remove the carets."
In R, please provide the code for the following: Install the EnvStats package and load the library. Use help(varTest) to open the information about the function varTest and read the documentation and notes about using this function Using the precip data set, create a sample of size 20. Use this sample to test if the standard deviation is greater than 15 square miles. Clearly state your hypotheses, rejection rule, and conclusion in your report. Use alpha = 0.05. Compute the population variance of the precip data set (note that the var() function gives the sample variance so you will have to scale it to obtain the population variance). Given this information, what do you think about your test results? Explain any discrepancies or issues that you see.

1.Based on your analysis/ identify the searching type of the code snippet. Then describe the searching best case and worst case. 2.Show and describe 2 statements from the code snippet that it is the searching type based on your answer in (a). 3.The function in the code snippet above is not complete and at least 4 additional statements are needed to complete the code. Show the possible full code for the function and briefly explain any modifications to the code snippet. 4.The problem of the searching technique indicated in the searchitem function is the complexity in the order of n. Thus,a hash table is used. Let Say if we have eight persons with their IDs need to be stored in the hash table as follows: 147354864,834185952,735489973,135152056,616500306,106500306, 217540406, and 177357855. 4a)Using hash table size of 10, write the hashing function and show the hash table for all the IDs. 4b)There should be a collision in your hash table in (i). Thus, construct a hashing function based…

C ( answer fast please) Q1. Write a MATLAB code to obtain the following. Keep your code commented whenever required. Copy your source code and outcomes from command widow also add screen shots of any figures in your solution (3.0) Create a function called ‘My_Calc’ that satisfies the following criteria:. For x <4, f(x)= x^3; For x ≥4 and x<8 f(x)= x^2; For x ≥8, f(x)= 8.x; Plot your results for values of x from -5 to 25. Choose your spacing to create a smooth curve.
True or False If there is a past estimation error, there is a need to replace the property immediately.
Add a validation function using Javascript that does the following 2 things: validates that password entered by the user and reentered password match. Note that minlength ensures it's a minimum of 8 of characters. Test thoroughly!!! Note that usually you would want to check that password meets some minimum requirements such as it includes both upper and lowercase letters and either a number or special character. In Javascript, we use regular expressions to do this. For this assignments, just make sure the password and reentered password match. validates that the username isn't already taken. Create an array of existing valid usernames. Include Harry, Elizabeth, and Shana.
For the assignment, be sure to run unmodified code, but you are free to play around with the code to try out different parameters or different implementations. The functions don't necessarily do anything in particular, but does a lot of basic operations on 8 variables. Note that function1 and function2 do NOT produce the same result, but they do similar amounts of operations. Look at the differences between function1 and function2 What is the difference (apart from what the function does)? Do the two functions do the same amount of computation? If so, do you think that the two functions will run in the same amount oftime? #include <stdio.h>#include <time.h>#include <stdlib.h> int function1(int a, int b, int c, int d, int e, int f, int g, int h, int n) { for (int i=0; i<n; i++) { a = h + g; b = a - h; c = b + a; d = c - b; e = d + c; f = e - d; g = f + e; h = g - f; } return h;} int function2(int a, int b, int c, int d, int e, int f, int…
Which of the following statements about functional-style programming is false? With functional-style programming capabilities you can write code that is more concise, clearer and easier to debug (find and correct errors). The min and max functions are examples of a functional-style programming concept called reduction. They reduce a collection of values to a single value. Other reductions you’ll see include the sum, average, variance and standard deviation of a collection of values. All reductions are built into Python—you cannot define custom reductions.
Enter two correct assertEqual tests for the computeCircleArea function described below. Note: to round a result to two decimal places in Matlab, use the round function like this: round(answer * 100)/100 since Matlab's round function only works for integers.
