STAT 103 Sample Questions for the Final Exam
... 14. An environmentalist group monitors the temperature rise in the water 50 yards downstream from a nuclear power station. Federal regulations permit a rise in temperature of 3.0°F. They collect 16 water samples and obtain a mean rise of 3.2°F with a standard deviation of 1.0°F. Does this show that ...

... The standard deviation is found by finding the square root of npq n=the number of values in the sample which would be 100. p=the percent of Fruit Loops that are said to be blue or 0.33. q=the probability of 1p or 1-0.33 which is 0.67. So, the standard deviation is the square root of 100x0.33x0.67 or ...

IB Math Analysis
... The heights (in inches) of young women follow the N(64.5, 2.5) distribution. The random variable X is the height of a randomly selected young woman. In this activity, you will use GDC to randomly sample from this distribution and then use post-it notes to construct a distribution of averages. 1. Wha ...
