09.07 Task 1—Normal Distribution Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a…

my eye. The first being the one labeled “Then and Now” which shows the difference in percentages from 2004 to 2013 in whether people described themselves as optimists or pessimists. The percent of Optimist decreased from 70% to 50%, which can only mean that more people negatively view the aspects of things which questionably brings up the question to why more people think this way?

Conclusion The hypothesis stated that, “If the amount of water a seed receives is increased, then the amount of seeds that sprout will increase because seeds need water to germinate.” The hypothesis was supported however it is also refuted because, the amount of seeds that germinated declined in numbers at 100 drops/hour. Whereas before it increased for 0 to 71 from 0 drops to 75 drops/hour.The refined hypothesis states that if the amount of water a seed receives increases, then the amount of…

3. Results and discussion 3.1. Effect of pH on the percent extraction values of Sn(II) by SbS-DET. The effect of pH of reacting species such as metal ions and ligands for the formation of metal complexes is known to play a significant role in their removal and extraction processes [24]. To evaluate and identify the possible contribution of pH value of metal ion on the SbS-DET process for the formation of Sn(II)–(8HQ)2 complex via complexation and removal of Sn(II) from aqueous…
