<data1>
<result1>Qualitative Variable: Gender
Significance level: 0.05 or 95%
sample size: 30
margin of error: 0.011 = 2s/(square root) of n = 2(0.03)/5.48
confidence interval: 0.5 ± 0.011 ;
Level of Significance is at 0.05 or 95%: 0.489 < P < 0.511
<result2>The mean of the distribution is .0497. This is in between of the 0.45 and 0.5 brackets. The graph follows a normal distribution, however it is slightly left skewed, since more data is located on the right side.
<result3>First Quantitative Variable: Age
Sample size: 30
Margin of Error: 0.3 = 2s/(square root) of n = 2(0.82)/5.48
The confidence interval is 95%. There is a high certainty that the true sample mean lies between 30.54 and 29.94.
<result4>The data is normally distributed. It is a leftskewed, meaning most of the data is on the right side of the graph. you can see the mean of data (thin red line) is in the highest peaked subsection and lies between the intervals of 30 and 31. A bigger sample size may shift the distribution to a bell curve.
<result5>You can see that 18.34% of the data falls below the data value of 29.5.
<result6>Second Quantitative Variable: Soda
Sample size: 30
Margin of Error: 0.64 = 2s/(square root) of n = 2(1.74)/5.48
The cofidence interval is 95%. There is a high certainty that the true sample mean lies between 19.22 and 17.94.
<result7>The data is normally distributed. It is a rightskewed, meaning most of the data is on the left side of the graph. you can see the mean of data (thin red line) is in the second highest peaked subsection and lies between the intervals of 18 and 20. A bigger sample size may shift the distribution to a bell curve.
<result8>You can see that 86.50% of the data falls below the data value of 20.5.
