Question

There are dozens of personality tests available on the World Wide Web. One test, scored on a scale of 0 to 200 , is designed to give an indication of how "personable" the test taker is, with higher scores indicating more "personability." Suppose that scores on this test have a mean of 99 and a standard deviation of 21 . Complete the following statements about the distribution of scores on this personality test.

(a) According to Chebyshev's theorem, at least----- of the scores lie between 57 and 141.

(b) According to Chebyshev's theorem, at least 36% of the scores lie between ----and----- . (Round your answer to the nearest integer.)

(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the scores lie between -----and ------.

(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately------- of the scores lie between 57 and 141.

A nationwide test taken by high school sophomores and juniors
has three sections, each scored on a scale of 20 to 80. In a recent
year, the national mean score for the writing section was 50.4,
with a standard deviation of 9.1. Based on this information,
complete the following statements about the distribution of the
scores on the writing section for the recent year.
A. According to chebyshev's theorem, at least____of the scores
lie between 23.1 and 77.7.
B. According...

A major cab company in Chicago has computed its mean fare from
O'Hare Airport to the Drake Hotel to be $29.98 , with a standard
deviation of $4.08. Based on this information, complete the
following statements about the distribution of the company's fares

Students at a major university are complaining of a serious
housing crunch. Many of the university's students, they complain,
have to commute too far to school because there is not enough
housing near campus. The university officials respond with the
following information: the mean distance commuted to school by
students is 16.2 miles, and the standard deviation of the distance
commuted is 3.1 miles. Assuming that the university officials'
information is correct, complete the following statements about the
distribution of...

From the time of early studies by Sir Francis Galton in the late
nineteenth century linking it with mental ability, the cranial
capacity of the human skull has played an important role in
arguments about IQ, racial differences, and evolution, sometimes
with serious consequences. (See, for example, S.J. Gould, "The
Mismeasure of Man," 1996.) Suppose that the mean cranial capacity
measurement for modern, adult males is 1145 cc (cubic centimeters)
and that the standard deviation is 262 cc. Complete the...

BIG Corporation produces just about everything but is currently
interested in the lifetimes of its batteries, hoping to obtain its
share of a market boosted by the popularity of portable CD and MP3
players. To investigate its new line of Ultra batteries, BIG
randomly selects 1000 Ultra batteries and finds that they have a
mean lifetime of 834 hours, with a standard deviation of 81 hours.
Suppose that this mean and standard deviation apply to the
population of all Ultra...

One personality test available on the World Wide Web has a
subsection designed to assess the "honesty" of the test-taker.
After taking the test and seeing your score for this subsection,
you're interested in the mean score, μ, among the general
population on this subsection. The website reports that μ is 145,
but you believe that μ is greater than 145. You decide to do a
statistical test. You choose a random sample of people and have
them take the...

There is some evidence that, in the years , a simple name change
resulted in a short-term increase in the price of certain business
firms' stocks (relative to the prices of similar stocks). (See D.
Horsky and P. Swyngedouw, "Does it pay to change your company's
name? A stock market perspective," Marketing Science v6., pp.320-35
.) Suppose that, to test the profitability of name changes in the
more recent market (the past five years), we analyze the stock
prices of...
