This is the process by which organisms with favorable traits are able to produce more offspring.

A confidence interval comprises of the point estimate, standard error, and this.
What is multiplier?
If we are conducting a one sample hypothesis test using the Student's t distribution and our sample comprises of 28 units, then our degrees of freedom are...
What are 27?
King Arthur famously pulled this sword out of a stone.
What is Excalibur?
The sample standard error for the sampling distribution of the sample mean is calculated using this formula.
What is \frac{s}{sqrt{n}} ?
This fruit is high in potassium and also spelled out in Gwen Stefani's song "Hollaback Girl."
What is a banana?
This is the largest mountain range in North America, spanning both the United States and Canada.
What are the Rocky Mountains?
Confidence is written as 1-alpha, where alpha represents this.
What is the level of significance?
Say we have an assumed population mean of 78.2 and population variance of 4.8, this is the value in the 10th percentile.
What is 75.39?
The Student's t distribution was developed by William Sealy Gosset while working for this company.
What is Guinness?
The continuous probability P(a<=Z<=b) can be rewritten as this formula.
What is

Recently, Yellowstone National Park rangers have needed to ask the general public to stop trying to take selfies with this herd animal.
What are bison/buffalo?
This was the largest contiguous empire in the world, for nearly 2 centuries, spanning from modern-day Hungary to China.
What is the Mongol empire?
This is the type of statistical error that occurred if the null hypothesis was wrongly rejected.
What is a Type I Error?
Given our alternative hypothesis is one-sided and sample size is 14, this is our critical value for 99% confidence.
What is t_{13,0.01}=2.65 ?
This type of avian raptor both starts and end with the letter "e."
What is an eagle?
When formulating the statistical hypotheses, this hypothesis is more important than the other.
What is the null hypothesis?
This country, in terms of area, is the largest on its continent and the fifth-largest in the world.
What is Brazil?
This is considered to be the hottest desert in the world, but not the largest.
What is the Sahara?
This is the formula for the test statistic when the population variance is unknown.
What is t^**=\frac{\barX-\mu}{\frac{s}{\sqrt{n}}} ?
Say we were to conduct a two-sided hypothesis test with a hypothesized null value of 100 and our sample statistics, based on a sample size of 18, are
\barX=102.5 and s=5.3
Against the level of significance
alpha = 0.05
what is our conclusion drawn?
What is fail to reject?
A Harvard researcher, interested in the opinions of highly-educated people about a major political issue, randomly surveys students on the Harvard campus as they are walking between classes as their sample.
The researcher likely committed this type of sampling error.
What is selection bias?
When calculating the p-value, the formula used is dependent on whether this is one-sided or two-sided.
