DESCRIBE THE FUNCTIONS OF
PRELIMINARY DATA GATHERING?

Assume that you have a sample of n1 =9, with the sample mean X1 =40, and a sample standard deviation of S1 =5, and you have an independent sample of n 2=15 from another population with a sample mean of X2 =33, and the sample standard deviation S2=6. Construct a 90% confidence interval estimate of the population mean difference between 1 and 2 . Assume that the two population variances are equal. 1 2 Conduct a critical analysis to the RESPONSE, listed below, (IN BOLD), In no less than 200 words. Responses must demonstrate clear, insightful critical thinking.Question(s):1. Plot your career highs, lows and plateaus on a graph with job satisfaction as the vertical axis and time in years (starting with your first job) as the horizontal axis. Please add your graph to your post.2. What do the highs and lows have in common?Response:There are multiple jobs I have had within these past 6 years. In total I have had about 5 jobs. My very first job was Jack in the Box and I started working during my senior year of High School. I was only there for a short amount of time due to the fact that I was going to be attending college and I had to quit since I was moving closer to school. There were a lot of low moments when working here. Some of things that I see in common with "low" job satisfcation will have to do with the times I work in fast food chains. During this type of environment, managers were very demanding of us. I as well had encounters with managers being disrespectful to me and yelling at me in front of customers. Which was not good for my mental health since the things she would express to me would just bring me down and it was to the point that at home I would come with a negative attitude. Due to this, my job satisfaction was very low and I no longer was happy in the workplace. I would leave the company within a couple of months of just working there.What I seem to have in common will be Dollar Tree and Walmart I worked in for the longest time. Which goes to show that there was a lot of job satisfaction. The thing about both of these jobs is that both my managers were very supportive and it was a job that I enjoy coming into. I see that both of these jobs were retail based jobs and I believe because of the interaction I made with customers is the reason why I spent a couple years with the company. As well, in Walmart we would get a pay increase every six month and a bonus every quarter and I was not even a full time employee which made me feel more appreciated of my job. Which goes to show why I had a higher job satisfaction. Johnny's Detailing Shop started the year with total assets of $60,000 and total liabilities of $40,000. During the year the business recorded $105,000 in revenues, $55,000 in expenses, and dividends of $10,000. Compute stockholders' equity at the end of the year. Example of Answer: 4000 (No comma,-space, decimal point, or $ sign) Answer: 55000 Assume that Corn co. sold 7,600 units of product A and 2,400 units of product B during the past year. The unit contribution margins for product A and B are $25 and $64, respectively. Corn has fared costs of $346,000, The break-ven point in units isa. 10.070 unitsb. 15.105 unitsC. 12.064 units d. 6.806 units trenches and island arcs are found at spreading centers. Determine the x - and y-intercepts for the given function. Write your answer as an ordered pair. s(x)=4x28 If there is more than one answer, separate your answers with commas. Select "None" if appropriate. Part 1 of 2 xintercept(s): Part 2 of 2 y-intercept(s): Experiments are often impossible to implement because some treatments are too important to be decided by researchers difficult to explain in public difficult to collect sufficient control variables may not "scale up" This unit's readings included information on pricing. You are introduced to the shutdown price, using elasticity to determine the effects of price changes, and cost-based pricing. Discuss the importance of considering elasticity in pricing decisions and the danger of relying solely on costs. A wooden block with mass 1.15 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 29.0 (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 7.55 m up the incline from A, the block is moving up the incline at a speed of 6.25 Im/s and is no longer in contact with the spring. The coefficient of kinetic friction between the block and incline is 0.45. The mass of the spring is negligible. Constants Part A Calculate the amount of potential energy that was initially stored in the spring. Take free fall acceleration to be 9.80 m/s^2.

Agribusiness models b. Coupled socio-ecological systemsc. Adaptive co-management d. Globalisation How does culture shape the way relationships are formed, maintained, and/or ended? You are offered an investment with the following conditions: - The cost of the investment is $900. - The investment pays out a sum X at the end of the first year; this payout grows at the rate of 9% per year for another 10 years. If your discount rate is 13%, calculate the smallest X which would entice you to purchase the asset. 2. You just took a $30,000,10-year loan. Payments at the end of each year are flat (equal in every year) at an interest rate of 13%. How much is your payment at the end of each year? Calculate the appropriate loan table, showing the breakdown in each year between principal and interest. __________ helps project teams ensure that systems are designed efficiently and installed appropriately.
