Irradiation of food for the purposes of extension of shelf life, control of microbial load, reduction of pathogenic microorganisms and disinfection is regarded by many consumers with suspicion. One reason is the lack of methods within food-controlling laboratories which can detect irradiation treatment ...
If a random sample of size n = 30 is obtained, what is the probability that the mean is less than 96? Consider a population of 200 with a mean of 55 and a standard deviation equal to 23 . What is the probability of obtaining a sample mean of 58 or less from a sample of 45 ?

Volatilityis also positively correlated with an option's price since the greater the price movements of a stock or other asset, the more chances those large moves will produce an in-the-money option. Because of this, volatility plays a key role in pricing options. At the same time, market ...
Homologous artificial insemination (HAI) or conjugal artificial insemination (CAI), i.e. using a sample from the couple. The probability of pregnancy in this case is close to 15-25%. Heterologous or donor artificial insemination (DAI), with bank sperm. The success rate of DAI is 20-30%. ...
Additionally, we applied group-mean centering to non-binary individual-level predictors. Our multilevel model was specified as a random-intercept, fixed-slope model. Results Ecological tests The results of the multi-level analysis in Table 1 contrast the individual-level and country-level effects ...
security. It is represented by the symbol Δ. The delta also tells options traders thehedging ratioto become delta neutral. A third interpretation of an option's delta is the probability that it will finishin the money. Delta values can be positive or negative depending on the type of ...
Inspired by this fact, we here propose a new agent–based model to capture the whole picture of the joint action of the three mechanisms in information spreading, by quantifying the complex contagion mechanisms as stickiness and persistence and carry out extensive simulations of the model on ...
Our results suggest that a one standard deviation increase in policy uncertainty is associated with an 11.74% decline (i.e., a drop in the unconditional mean likelihood from 14% to 12.35%) in the probability of a firm announcing an acquisition the next year. In addition, we find no ...
children’s performance on a latent factor ‘number knowledge’ which included children’s performance in number writing of six numbers (including two two-digit numbers) at school entry (mean age 5 years) was a significant predictor of their arithmetic development over their first year in school....
