Find the percentile.
We flip a coin \(100\) times \((n = 100)\) and note that it only comes up heads \(20% (p = 0.20)\) of the time. The mean and standard deviation for the number of times the coin lands on heads is \(\mu=20\) and \(\sigma=4\) (verify the mean and standard deviation). Solve the following:
a. There is about a \(68%\) chance that the number of heads will be somewhere between ___ and ___.
b. There is about a ____chance that the number of heads will be somewhere between \(12\) and \(28\).
c. There is about a ____ chance that the number of heads will be somewhere between eight and \(32\).
Suppose a normal distribution has a mean of six and a standard deviation of 1.5. What is the z-score of x = 5.5?
Suppose . Between what values does of the data lie?
What is the z-score of x= , if it is standard deviations to the left of the mean?
