Chi-square test

A sample revealed three bags of 56, two bags of 57, one bag of 55, and two bags of 58.

These results produced a chi squared value of 5.230. The p-value calculated from this lab was .022. A chi squared value of .022, less than the benchmark of .05 means the data from the lab was significant and statistically rejects the null hypothesis that there was no correlation between residency and aggression between male crickets. The null hypothesis suggested the wins should have been equal at 239 wins for the intruder and 239 wins for the resident. If the chi squared test resulted in a…

volunteering with American Public Square. I have completed around eleven hours so far and have been helping at events hosted by the group. At events I have helped attendants find seats, passed out programs, collected questions from the audience, tracked demographics, and cleaned up once attendees have left. While my acts have seemed small to me, those putting on the programs have said these little things amount to a large burden off their shoulders. From American Public Squares website it is an…

Communal Areas Cleaning London Do you own a large commercial property, student property, flat share or office block? If you do, then you will have to address cleaning communal areas. The reason is because you must provide residents or visitors to such property with healthy living conditions that stand up to certain standards. You could try and take on such task on your own, but odds are it will be too large a job. By outsourcing the job to a communal areas cleaning company, you can take the…

children will be free the noise (Mayesky, 2015). Space requirements: My ideal infant classroom would be for 8 infants between ages between 6 weeks to 12 months. It would have a proximity of 500 sq. feet where each child should have a minimum of 35 square feet of usable indoor floor space and 30 sq. feet of sleeping space per child. I should have a minimum 2 feet between the cribs. Also, we would provide a napping area that is separated from the playing area and a quiet area for snoozing…

A Description of the Problem For the problem-solving report, we have a 4x4 grid that we have to find as many rectangles as we can. The rectangles that can be found on the 4x4 grid ranges from 1x1 rectangles to a 4x4 rectangle. According to MathisFun.com a rectangle is, “a 4-sided flat shape with straight sides where all interior angles are right angles (90°). Also opposite sides are parallel and of equal length. Example: Another factor we have to consider is the lines provided on the 4x4 grid…

Akkadian. It says, On Triangles, written by Sudines. And the spell? It’s a theorem that can find the length of the hypotenuse of any right triangle. It’s amazing, but it’s not witchcraft.” Using the chalk he sketched out two square frames, each filled with different shapes. “The square frames are equal in size, but there are different shapes in them. Does everyone agree?” He didn’t wait for the crowd to reply, and instead labeled each side of a shape as a, b, or c. “So each side is either one of…

buildings are huge and there are so many people. I am standing on the corner of W 47th street and Broadway, standing in front of a Starbucks. I should probably find a hotel.. I pull my phone out of my pocket and pull up google maps. I find the Night Time Square right down the road just past 7th Ave is only about $88 a night, so I grip the straps of my backpack and start walking. I walk past the Phantom of Broadway store and take a quick peek inside and notice all of the broadway shirts and other…

Ever noticed how quickly time fly’s by? A single day retains only twenty-four hours; ones individual life is contrived up of these single seconds, hours, and minutes. Before it’s even realized that time has passed. How that time was spent is inconsequential. I realized that no matter how that time was used; that day will come to a halt. When it ends there is a series of questions you can ask yourself. In my opinion there is one question that trumps the others. Did I have a positive effect on the…
