Introduction Sloth bears are mostly found in the tropical and subtropical regions of the Indian subcontinent. Their inhabitation ranging from the foothills of the Himalayas to the southern end of the Western Ghats mountain range in India as well as in the island of Sri Lanka (Prater, 1965). The number of Sloth bear distributed in the Indian peninsula was estimated to be approximately 7,600 (Jaffeson, 1975). Two subspecies of sloth bear, namely Melursus ursinus ursinus and Melursus ursinus…

The effects of gender on an individual’s level of conformity: a modification of the Asch experiment Abstract Both males and females readily conform their judgments and actions to peer groups, which has been recognised as advantageous (Haun & Tomasello, 2011). What we wanted to know, however, was whether males or females conformed more often. In this experiment, we replicated the Asch conformity experiment whilst focusing on differences in gender. We examined these inter-gendered differences…

as a miss (7.2%). Miss rates did not vary significantly across gaze conditions or eccentricities. Error rates were calculated as the number of false alarms (e.g., pressing the AG button when a DG face was presented, or vice versa) that were made out of the total amount of responses that could have been made for each individual eccentricity. As this was a two-button press, forced choice task, a 50% error rate to a particular condition was chance level performance. Response rates were also…

Taq DNA polymerase can cause error because it does not have the ability to proof read, resulting in faults in amplification. More the amplification there are higher chances of errors to formed (Wilson et al, 1985). The serious drawback of PCR is that the enzyme is prone to error which can cause mutations in the fragments. If the binding of the primer is not specific, then the specificity of fragment can…

the law, leaving the remaining 6.25% disagreeing with the law. To calculate the margin of error, I utilized the online calculator given in the survey instructions. First I entered UTSA’s population size, followed by the sample size of students I have surveyed, resulting in a margin of error of 24.49. Next, I needed to calculate the 95% confidence interval by using my approval percentage and margin of error. To get my approval percentage of 93.75% I divided the amount of students who agreed…

distribution. This results in greater estimates of standard error. This is a problem. Slide 7: Let’s talk about beer. Yes, beer. W.S. Gossett, a scientist for Guiness brewery, pondered how each bale of barley affected the quality of the beer produced. As a result of his work, he produced the Probably Error of the Mean and the t-test Table which consider the differences between two groups by looking at their means while weighing their sample error that is influenced by sample size. Slide 8:…

However, there could have been errors in the first part of the lab that could have affected the chart and the understanding on how I should have labeled each branch. On the first part of the lab, my errors may have been involved with the miscalculations of the distance. Perhaps two branches similarly related could have been switched and corrected. Fuerteventura and Lanzarote are closer to each other that it may be easier to mistaken their place on their charts. Another error could have been the…

of brand switching of selected milk products in Abia State, Nigeria. Specifically, determine the most preferred milk brand in Abia State, ascertain the likeliness of switching brand, among others. A multi-stage sampling technique was used for selecting location while a simple random sampling was used for selecting respondents. A structured questionnaire was administered on three hundred respondents (300) and a total of two hundred and ninety (290) questionnaires were duly completed and returned…

findings thoroughly, the article left out key information about Munsch’s data and a few other crucial conclusions she mentions. Munsch mentions in her article that the NLSY97 oversamples black and Latino populations, but Wallace does not note any sampling errors. In addition, Wallace does not discuss all the conclusions that Munsch describes in the study. Wallace does spend much of the article discussing how the pressure of gender roles and more working hours makes women less likely to cheat in…

Theoretical Framework The Proportional Odds Model A binary logistic regression model estimates the odds and the probability of experiencing an event for the dichotomous outcome variable on a set of predictors. The logistic regression model is defined as: ln(Y′) = logit [π(x)] = ln = α + β1X1 + β2X2 + …+ βpXp. (1) where logit [π(x)] is the log odds of success, and the odds is a ratio between the probability of having an event and the probability of not having that event.…
