The Confidence Interval Applet lets you simulate large numbers of confidence intervals quickly. Select 95% confidence and then sample 50 intervals. Record the number of intervals that cover the true value (this appears in the Hit box in the applet). Press the Reset button and repeat 30 times. Make a stemplot of the results and find the mean. If you repeated this experiment very many times, what would you expect the average number of hits to be?

a.47.5
b.95
c.0.95
d.50

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
