The director of admissions at the University at the University of Maryland, University College is concerned about the high cost of textbooks for the students each semester. A sample of 25 students enrolled in the university indicates that x(bar) = $315.40 and s = $43.20.
A mean that is not in a confidence interval is rejected by the confidence interval, and we say the evidence against the mean is significant. At the 0.10 level of significance, is there evidence against mean $300?
- No, because 300 is below the lower limit of the confidence interval
- Yes, because 300 is below the lower limit of the confidence interval
- No because 300 is in the confidence interval
- Yes, because 300 is in the confidence interval

TABLE 12-11 The director of admissions at a state college is
interested in seeing if admissions status (admitted, waiting list,
denied admission) at his college is independent of the type of
community in which an applicant resides. He takes a sample of
recent admissions decisions and forms the following table:

The director of admissions at a large university advises parents
of incoming students about the cost of textbooks during a typical
semester. He selected a sample of 100 students and recorded their
textbook expenses for the semester. He then calculated a sample
mean of $675.60 and a sample standard deviation of $45.20. You may
assume that the distribution of textbook expenses is approximately
normally distributed.
(a) Is there sufficient evidence that the population mean
textbook expense per semester is above...

The director of admissions of a small college selected 120
students at random from the new freshman class in a study to
determine whether a student's grade point average (gpa) at the end
of freshman year can be predicted from the ACT test score.
(a) Read in the dataset (it is in the le named ACT.txt ).
(b) Obtain the least-squares estimates of intercept and slope,
and state the estimated regression function.
(c) Plot the data and the estimated regression...

An admissions director wants to estimate the mean age of all
students enrolled at a college. The estimate must be within 1 years
of the population mean. Assume the population of ages is normally
distributed and the population standard deviation is 9.5 years.
Determine the minimum sample size required to construct a 80%
confidence interval for the population mean age. Determine the
minimum sample size required to construct a 95% confidence interval
for the population mean age. Which level of...

A college admissions director wishes to estimate the mean age of
all students currently enrolled. In a random sample of 81 students,
the mean age is found to be 20.51 years. From past studies, the
standard deviation of the population is known to be 2 years, and
the population is normally distributed. Construct a 99% confidence
interval of the population mean age. (Round off final answers to
two decimal places, if appropriate. Do not round off numbers taken
directly from...
