Arithmetic mean

The statistical test used in this experiment was a Chi-square test because it measures the goodness of fit. There were 370 trials performed in the overall experiment. The sample size in the experiment was 740. Each cricket whether it was labeled intruder or resident had an observed and expectant number times it should win. For the resident crickets, it was expected that the cricket would win 185 times in the experiment. The observed value was calculated to be 238 wins in the experiment as well.…

the global database participants used at the test. After using SPSS it was discovered that the p-value was .000. The mean for digit span when it came to presenting single digits at a time was 7.46. The mean for digit span when it came to presenting group numbers was 8.95. The group number mean was 1.40 higher than the single digit. The mean for the binary single was 7.7 and the mean for letters was…

to do it. In addition, I’ve achieved expected learning objectives through practical exercises of the course. The journey began with descriptive statistics; measures of central location and dispersion. The very common measure of central tendency; mean, median and mode. Whereas variance and standard deviation were discussed as measure of dispersion. I 'm also actively participated in doing the exercises for both measure of central tendency and dispersion using hypothetical data given with the…

The effect of in or out-group membership of a critic on personality sensitivity Daniel Middleton Abstract Background Group membership creates a social identity that results in in-group favourtism, as a result in-group members distrust out-group members. However, little research has been conducted into the threat that arises from whether criticism is from an in-group or an out-group member. Aim The aim of this study was to compare personality sensitivity perception…

Pre-Lab Questions 1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size. 2. There are two methods of sampling, direct and indirect. Direct sampling is an…

diversification among the 20 stocks that remain in his portfolio. This entails maintaining a low correlation among the remaining stocks. For example, in part (a), with ρ = 0.2, the increase in portfolio risk was minimal. As a practical matter, this means that Hennessy would have to spread his portfolio among many industries; concentrating on just a few industries would result in higher correlations among the included stocks. 2. Risk reduction benefits from diversification are not a linear…

The reason that rule does not follow along with that rule is because I took the amount of states there are which is fifty, then multiplied it by sixty eight percent making the nube come to a total of thirty four which mean there should have been a total of thirty four people in the amount ranging between four and nineteen states which actually came to a total of forty people making it the percentage not sixty eight percent. There was also the ninety five percent which…

When conducting a hypothesis test for the difference between two means it’s essentially called a two sample t-test. According to Dr. Mirabella (2011, p. 5-2) states that, “In each case you can conduct a t-test for independent means to determine if a significant difference exists.” Furthermore, we’re conducting this test to see if there is an overlapping or if there is clearly a difference among the GPAs for men and women. In our case we are comparing the GPAs for a sample of men and a sample…

the four seasons, humid environment, rainy winter weather and the prevailing wind is south and southwestern (Amer and Abou Hamed 2011). The average value of the diurnal highest temperature in Tartous is in summer in August with about 30◦C, and the mean value of the minimum temperature is in winter in January with about 7◦C, and the average of humidity between 60-75% (Meteorological center of Tartous 2015).. Heat and humidity are the main issues that need to be…

a. Explain in details about the CBIS. (5 marks | 100-150 words). Based on the case 1 in my opinion the 2 type CBIS that suitable for the case is straregic information system and manegement support system. Strategic information systems (SIS) are information systems that are developed in response to corporate business initiative. They are intended to give competitive advantage to the organization. They may deliver a product or service that is at a lower cost, that is…
