Mr. Dan Selig, president and CEO, would like to know the characteristics of his checking account customer. To better understand the customers, Mr. Selig asked Ms. Wendy Lamberg, director

as our organism. Data Analysis After conducting the experiment, statistical analysis was done to see how the observed results compared to expected results (hypotheses). ). The data was obtained from blackboard and put it into Excel along minute intervals of 1-20. A table was set up in excel to include 5 replicates, average temperatures,

RESULTS The baseline study of the elderly study sample are as shown in the given table. It can be observed that three-fifths of the total sample were composed of women, and also an expression of the high prevalence of diabetes, antihypertensive treatment, and CVD are evident. Table 1: Baseline characteristics of the study sample Characteristic Value Clinical features     Women (%) 62.3     Age (years) 79.0 ± 4.5     Systolic blood pressure (mmHg) 143 ± 21     Diastolic blood pressure (mmHg) 72

descriptive statistics of this question: The range of ages of the subjects was from 20 to 37. The mean subject age was 22.53 years old. Standard deviation was 2.134 years for the subject pool. The 95% confidence interval was between 22.11 and 22.95 years old. This confidence interval indicates that we are 95% confident the mean age of college recreational runners is between the ages of 22.11 and 22.95 years old. The age of the subjects is skewed to the right. This suggests that there

Additionally, of equal importance was determining an ideal sample size. A couple of factors played a role in coming to an ideal size as we asked ourselves “how accurate do we want the sample data to be?” We considered margin of error (or confidence intervals) and confidence levels. The first factor, margin of error, is defined as “a range of values derived from a statistic for a random sample that is likely to include the corresponding population parameter” (Gall, Gall & Borg, p. 577, 2015). In simpler

typical these typical central values are). These statistics are relevant to calculate because they allow for more meaningful calculations that allow us to draw more specific and accurate conclusions about claims such as the standard error, confidence intervals, z-scores and statistical significance. The bar chart in Figure 1 shows the frequency that each Quebecker chose their feelings about Canada. It shows that a majority of respondents falls at 50 or above with the most frequent value is 100.
