Correlation
This number describes a population.
What is a parameter?
A house in a city is randomly selected and the residents are
asked about their TV watching habits. This is an example
which type of sampling.
What is cluster sampling?
This is either more than 1.5 times the IQR above
Q3 or below Q1.
What is an outlier?
This is generally a resistant measure of spread.
What is the IQR?
This set of numbers should be used to describe
skewed distributions.
What is the five number summary?
When drawing one card from a deck this is the probability of
drawing a queen or a heart.
What is 4/13 or 0.3077?
45% of teachers at Central High School have a master’s degree,
60% have 40 credits beyond their bachelors degree, and 25% have
a masters and 40 credits beyond their bachelors. This is the
probability that a teacher has a masters or 40 credits beyond their
bachelors.
What is 0.80?
Three cards are drawn from a deck of cards.
This is the probability that at least one of them
is a red card.
What is 0.8824?
The probability a kicker makes a field goal is 0.65. Given 30 field
goals this is the probability he misses 12 or fewer.
What is 0.7802?
This is the number of ways you can
have 22 successes in 30 trials.
What is 5,852,925?
A news report claims that the average number of hours spent on
Facebook per week by teens is 16 hrs. You decide to investigate this
claim by randomly sampling 35 students at a local high school. The
average for your sample was 14.5 hours with a standard deviation of
4.7 hours. This is the 95% confidence interval for the mean number
of hours spent on Facebook by students at this high school.
What is 12.885 hours to 16.115 hours?
A given city experiences a horrible outbreak of a
disease called “RAGE” which turns people who are
bitten into zombies. If the disease is diagnosed early
enough it can be cured, but giving the cure to people
who are not infected with “RAGE” has serious side
effects. If doctors assume that a patient who comes in
for “RAGE” testing is healthy what is the risk involved
with a TYPE II error?
What is a person infected with “RAGE” goes
untreated and eventually becomes a zombie
who infects others?
The following two-way table resulted from classifying each individual
in a random sample of residents of a small city according to level of
education and employment status .

If the null hypothesis of no association between level of education and
employment status is true, this is the expected number who earned at
least a high school diploma and who are employed full time?
What is 48.05 people?
The following table represents the Weights of
Students in Their Freshman Year in kilograms.
A claim is made that there has been significant
weight loss since April. This is the most

to test this claim.

What is a matched pairs t-test or a t-test for
means given dependent samples?
In 1997 it was thought 35% of people had brown eyes, 45%
had blue eyes, 15% had green eyes, and 5% had a color
different than these three. A recent study done on 120
randomly selected people found that 41 had brown eyes, 60
had blue eyes, 16 had green, and the rest had a different
color than these three. If a test of the claim that the 1997
distribution of eye color is significantly different than the
recent distribution is performed this is the value of the test
statistic.
What is 2.413 using the Chi Square Goodness of Fit Test?
Yards thrown per game by Tom Brady are normally
distributed with mean 315 yards and standard deviation
15 yards. This is the percent of his games where he will
throw between 285 yards and 345 yards.
What is 95% of his games?
This is the number of standard deviations an
observation is from the mean.
What is a z-score or standardized score?
Yards thrown per game by Tom Brady are normally
distributed with mean 315 yards and standard deviation
15 yards. In a randomly selected game this is the
probability that Tom will throw between 298 and 320
yards.
What is 0.5020?
Yards thrown per game by Tom Brady are normally
distributed with mean 315 yards and standard deviation
15 yards. In a random sample of 5 games this is the
probability that the mean number of yards thrown is
more than 320 yards?
What is 0.2280?
The mean number of yards per game thrown by AFC Quarterback’s
is 280 yards with a standard of 17 yards. In the NFC the mean is
272 yards with a standard deviation of 12 yards. Tom Brady, an
AFC quarterback, threw 315 yards in a given game. Aaron
Rodgers from the NFC threw 300 yards in a given game. Which
quarterback performed better with respect to their conference?
Briefly explain.
Who is Aaron Rodgers? His amount was 2.33 standard deviations
above his group’s mean versus Tom’s who’s was only 2.05 above the
AFC average.
This statistic measures the percent of the variation in the
response variable that is explained by the LSRL on the
explanatory variable.
What is the coefficient of determination(r-squared)?
The equation below is an LSRL that describes the
relationship between Operating Cost(y-hat) and Number of
Passengers(x).
y-hat=1136+14.73x
This is the predicted Operating Cost for 325 passengers.
What is $5,923.25?
The equation below is an LSRL that describes the
relationship between Operating Cost(y-hat) and Number of
Passengers(x).
y-hat=1136+14.73x
This is the average Operating Cost Per Passenger.
What is the slope of the LSRL? In this case it is $14.73.
The correlation between Hours Studied and Score on the Final
Exam is 0.8502. What is the new correlation if a 5 point curve
is added to everyone’s final exam score?
What is 0.8502? Adding the same value to every point only
shifts the points. It does not change the correlation.
The LSRL below describes the relationship between
average touchdowns (y-hat) and passing yards(x) for 20
NFL quarterbacks.
y-hat=6+0.0014x
This is the residual for a quarterback who threw for 210
yards with 3 touchdowns.
What is -3.294?
