...?**Statistical** Tests Introduction There is an ample amount of evidence in the literature that heart and body size are correlated3&15. It is believed that individuals with large body size will generally possess a larger heart as opposed to smaller individuals. The cardiovascular system functions by pumping blood to meet the metabolic requirements of the tissues. To fulfil these metabolic requirements it is suggested that the heart rate of smaller individuals should be greater than the heart rate of large people. This theory is based on the concept that a heart with small size will have smaller cardiac output as compared to the larger heart. Hence, this scientific theory proposes that the heart beat of the larger individual will beat slowly...

...?Situation Imagine that you can predict the s scores on the Tests for Understanding in this In Week there was a bimodal **distribution**. In Week 2, there was a positive skew. In Week 3, there was a normal **distribution**. In Week 4, there was a negative skew. Questions: 1. What do these different scores tell you about the tests in Weeks 1, 2, 3, and 4? What is happening to the students' scores over time? From the given **distributions**, one can say that there is a distinct change in the pattern of student’s scores on understanding over the three weeks. Initially, there was a bimodal **distribution**, showing that students were grouped into those that understood better (scores that clustered around the top of the scale) and those that did...

... the frequency **distribution** table: Age Frequency 16-27 26 28-39 9 40-51 5 52-63 1 64-76 9 From this frequency table, we can see that the data are skewed to the right. If we were to graph this table, we would understand that the mass of **distribution** is concentrated more on the left-hand side. This is because there are relatively few high values, thus skewing the graph to the right. Because this graph would not contain a normal curve, we could predict a high number of people between the ages of 16 – 27 (26 out of a total of 50 — 26/50 = 0.52 or more than half).... there are 50 numbers, we can divide these numbers into groups of 10 (5 groups). Next we subtract the lowest number from the highest number (76 — 16 = 60). After this, we will divide...

.... Variance comes out as 1059. Standard Deviation is found out by calculating the square root of variance. Standard deviation is obtained as 32.54. The calculations are shown in Table 2.
This implies that the **distribution** can be defined by the mean and standard deviation as (161.5 +/- 32.54).

The average minutes that I use in physical fitness training, every day, is equal to 50.8. The figure is from data collected for duration of 10 days. The list number of minutes spent on physical fitness training is 38 minutes and the highest number of minutes is 60.

The standard deviation is the square root of the variance. The standard deviation of the above data is 9.33 meaning that, on average, every value of the collected data is far from the mean by 9.33 units.

Data falling within the range include 60,60,38,38,58,58,58,41,41,56, meaning that 100 percent of the sample is within the range. For normally distributed data, only 5 percent of the value should fall outside the above range. Therefore, the above data is normally...
