◉Standard deviation
Mean. Answer: A manager of a call center is in charge of creating a
staffing plan. The number of calls received per day is normally
distributed.
Which two statistics would be needed in order to estimate the
number of calls that would be received 95% of the time?
Choose 2 answers
◉picture of a hill. Answer: A hospital gathers the blood pressure
readings of a sample of patients. They find that mean, median and
mode of this data set are all nearly equal and that 50% of the blood
pressure readings are less than the mean and 50% are greater than
the mean.
Which histogram would correctly graph this data set? (hill)
◉68.2%. Answer: A normally distributed data set has a mean of 10
and a standard deviation of 2.
, What is the probability that a randomly selected event from the data
set will be between 8 and 12?
◉The dependent variable. Answer: A manager uses a linear
regression to examine how the store's retail sales are predicted by
advertising expenditures.
What will retail sales represent in this regression?
◉Sales of $45,432. Answer: An analyst used multiple linear
regression to explore how Store A's sales ( y) are predicted by Store
A's advertising expenditure dollars (variable x1) and the advertising
expenditure dollars of Store A's competitor (variable x2).
The estimated regression is y = 532 + 80.5 x1 - 35.6 x2.
Which scenario would be predicted if x1 is $1,000 and x2 is also
$1,000?
◉R-squared. Answer: A company decides to auction excess
inventory on an auction website. They have performed a regression
