Distribution Names
This distribution is symmetric, bell shaped, and is also known as the Gaussian distribution.
What is the normal distribution?
A _______ estimate is a statistic from a sample.
What is point?
Confidence intervals for means are __________, meaning the point estimate is smack dab in the middle of them (this is not the case for variances).
What is symmetric?
The symbol for the sample proportion.
What is p hat?
The acronym used to remember the order of the colors of the rainbow.
What is ROYGBIV?
In this type of distribution, each value of the random variable has an equal chance of appearing.
What is a uniform distribution?
The sample proportions follow a _________ distribution.
What is normal?
The sample means will follow a _________ distribution if we don't know the population standard deviation.
What is t?
The symbol for the sample mean.
What is X bar?
This number is known as the additive identity. It matters!
What is 0?
This is a family of distributions that look like the normal distribution, but have "fat tails." Take a sip, or spill it.
What are the t-distributions?
What is margin of error?
If we know the population standard deviation, what command do we choose in the calculator to create a confidence interval for the mean?
What is Z-interval?
The symbol for the population mean.
What is mu?
Ambergris was historically used in perfumes and came from this animal.
What is a whale?
This asymmetrical distribution family is used to create confidence intervals for variances. And no, it isn't cinnamon flavored.

If we construct a 99% confidence interval for mu, what percentage of the intervals will NOT contain the true value of mu?
What is 1%?
The symbol for the population standard deviation.
What is sigma?
For some time, this month was the beginning of the year in the Roman calendar. Beware a particular day in it...
