I'm running 2 simulations on how many times heads will appear when flipping a coin. The 1st simulation has 20 trials of 25 flips/trial (min= 0.32, max = 0.72, mean =.494, Standard deviation = 0.112596) and the 2nd simulation has 20 trials of 100 flips/trial (min=0.44, max=0.51, mean=0.503, standard deviation=0.047362). 1. What should we expect to happen as far as % of heads when coins are tossed...no matter how many times?
2. Describe the sampling model for 100 tosses.
3. Compare the “actual” distribution of your twenty sample proportions for 100 tosses to what the sampling model predicts.
4. Describe how your results might differ if you had run 1000 trials of the simulation instead of only 20.

Which of the following activities would conserve the most energy? installing a dimmer switch on a light using a blender instead of a food processor hanging clothes to dry on a clothesline instead of ironing them opening a window instead of turning on the air conditioning setting your computer's screen saver to turn on after less time has elapsed

In a recent telephone survey, 5,000 randomly selected teenagers were asked to cite their primary social network site. six of 10 teenagers said they use mybook as their primary social network site. a 95% confidence interval to estimate the true proportion of teenagers who use mybook as their primary social network site is found to be (0.2964, 0.9036). which of the following is a correct interpretation of the confidence level? ninety-five percent of all samples of this size would yield a confidence interval of (0.2964, 0.9036). there is a 95% chance that the true proportion of teenagers who use mybook as their primary social network site is in the interval (0.2964, 0.9036). ninety-five percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who use mybook as their primary social network site. ninety-five percent of all the samples of size 5,000 lie in the confidence interval (0.2964, 0.9036).
