Bootstrap versus sampling distribution. Most statistical software includes a function to generate samples from Normal distributions. Set the mean to 8.4 and the standard deviation to 14.7. You can think of all the numbers that would be produced by this function if it ran forever as a population that has the N(8.4, 14.7) distribution. Samples produced by the function are samples from this population.
(a) What is the exact sampling distribution of the sample mean x for a sample of size n from this population?
(b) Draw an SRS of size n = 10 from this population. Bootstrap the sample mean x using 1000 resamples from your sample. Give a histogram of the bootstrap distribution and the bootstrap standard error.
(c) Repeat the same process for samples of sizes n = 40 and n = 160.
(d) Write a careful description comparing the three bootstrap distributions and also comparing them with the exact sampling distribution. What are the effects of increasing the sample size?
In this programming assignment you will implement an open hash table and compare the performance of four hash functions using various prime table sizes.
Examine the corresponding ping reply packet. What are the ICMP type and code numbers? What other fields does this ICMP packet have?
If an address bus needs to be able to address 8-devices, how many conductors will be needed? What if each of those devices also requires to be able to talk back to the I/O control device?
Design a Visual C-Sharp program for an Ice Cream Shop. The program will store information about ice cream cones and customers.
An ATM allows a customer to withdraw a maximum of $500 per day. If a customer withdraws more than $300, the service charge is 4% of the amount over $300.
The following array is to be sorted in ascending order. Use the QuickSort algorithm to rearrange the array. Clearly show the internal state of the array after each pass of the sorting process.
Create an integer array withsome random 2-digit numbers. Move these numbers into a singly linked list with the same order. Display the contents of the array and linked list, respectively.
Using our Stack Data Structure for storing Disk objects (see attached zip file), implement the game The Towers of Hanoi for 3 disks and 3 columns (as simulated at: http://www.mathsisfun.com/games/towerofhanoi.html).
1. Suppose an initially empty stack S has performed a total of 25 push operations, 12 top operations, and 10 pop operations, 3 of which generated EmptyStackExceptions, which were caught and ignored. What is the current size of S?
Write a class that maintains the top 10 scores for a game application, implementing the add and remove methods but using a doubly linked list instead of an array. Program has to be written in java
