Stab Collection Agency has been known to purchase small accounts for $10.00 to collect a debt of $60.00. The profitable of this agency depend critically on the numbers of days to collect the debt‚ the size of the bill and the discount rate offer. QSCA has asked us to find a relationship between the size of the bill and the days collected if any. In this data set there’s variable DAYS is the number to collect the payment‚ and also the BILL would be the amount of the overdue bills. The data will define

A researcher thinks that if expectant mothers use vitamin pills‚ the birth weight of the babies will increase. The average birth weight of the population is 3.0kg. b. An engineer hypothesizes that the mean number of defects can be decreased in a manufacturing process of compact disks by using robots instead of humans

of 100 students which will represent our sample. We believe that since there are about 300 students in GPPI‚ a sample size of 100 is large enough to minimize the sampling error. As an additional step‚ we will conduct a balance test to make sure that the sample is not statistically different from the total population. Minimizing Coverage error: Since we have already got the complete list of students and email addresses‚ we have covered all the samples‚ thus the coverage error will be minimized

measure of accuracy. Depended upon calculation‚ Bootstrapping can be used to any statistic to measure estimation. Definition According to the Cambridge dictionary of statistics – “A confidence interval is a range of values‚ calculated from the sample observations that are believed‚ with a particular probability‚ to contain the true parameter value. A 95% confidence interval‚ for example‚ implies that were the estimation process repeated again and again‚ then 95% of the calculated intervals would

The effect of food source (mung bean Vigna radiata vs. black-eyed pea Vigna unguiculata) on relative inhibition of acetylcholinerase due to malaoxon in bean beetle Callosobruchus maculatus Background and Hypotheses: Recent studies‚ most notably Gbaye et al. (2011‚ 2012)‚ have investigated the sensitivity of bean beetles in the genus Callosobruchus to organophosphate insecticides (OPs). Economically this is important work given that these beetles are pests that threaten agricultural yields
