Suppose you are to test the mean difference between two independent samples in your data. The (unbiased) standard deviation in the first sample is 15, and it is 12 in the second sample. The sample sizes are 50 for the first and 100 for the second. Calculate the numerator of the pooled variance (numerator only, not the pooled variance itself).

The average of six numbers is 32. The average of the first three is 26. Find the fourth number if the average of the last two is 46.

Please reflect on which aspects of the topics you best & worst understood. Also describe how the topics in EACH part apply (or do not apply) to an application of your choice. Maybe a short paper, essay, etcTo be clear, the format can be like:1) Describe what topics were your strengths. Explain2) Describe what topics were your weakest. Explain3) Find an area (science/ engineering/ math/ etc...) of your interest where these topics may apply. Explain how they apply or do not apply

A long year-end status report for work is 153 pages long. You need to print 14 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.14 each.$Give your answer to the nearest cent, only for the paper you use (partial reams are OK)

A random sample of some of the heaviest carnivores on Earth was reviewed to determine if there is an association between the length (in meters) and weight (in kilograms) of these carnivores. Here are the scatter plot, the residuals plot, a histogram of the residuals, and the regression analysis of the data. Use this information to analyze the association between the length and weight of these carnivores. Hgram the ete Rasiduala Vera the Fited Vl Sertf htLeu The regression equation is Weight = - 668 + 485 Length Coef SE Coef 232.8 90.63 Predictor P - 668.3 -2.87 0.024 5.35 0.001 Constant Length 485.21 S = 194.794 R-Sq = 80.4% R-Sq (adj) = 77.6% Perform a significance test and state your conclusion in context.
