Student's t-distribution

This should express that a normal distribution will always follow this rule. Therefore, if one wanted to ensure that home sales were still tracking to normal distribution, a quick calculation would ensure it. If home sales or prices experienced an unusual circumstance, this calculation would allow one to see if the data were skewing positively or negatively. It is clear from the data in Table II that all four of the calculations are tracking to a normal distribution and all data points are…

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…

maximal positivity during the 300-500ms time range and FN400 was negative-going waveform (Figure 2-3). Paired samples t-tests were conducted to see if modality has an effect on the retrieval at Fz, FCz, F1 and FC2 (300-500ms). After analysis of the data found that there visual and acoustic brands did not differ according to voltage at Fz amplitude t(30) = 1.29, p = .206 and at FCz t(30) = 1.26, p = 216 (Figure 2, Graph 2). Additionally, the left and right lateralization was examined with F1 and…

and 53 males. b. There are 21 people under the age range of 13-35, which account for 21.6% of the total 97 in the sample. c. The mean level of the hour spent in the office during week 2 is 47.47 hours, with the standard deviation of 17.06. The distribution is slightly negative skew (-0.237), although in an acceptable range suggest that slightly more samples spend more hours in office than the average. The distribution’s value for kurtosis (-1.005) exceeds the acceptance level (value between 1.0…
