A college admissions officer for the school’s online undergraduate program wants to estimate the mean age of its graduating students. The administrator took a random sample of 40 from which the mean was 24 years and the standard deviation was 1.7 years.
If the mean age of online undergraduate students was 23 years of age, what is the probability that the sample of 40 would have produced a mean age of 24 or higher? Be sure to set up the two competing hypotheses and provide a statistical conclusion statement at a 5% level of significance for your results.

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...

A college admissions director wishes to estimate the mean age of
all students currently enrolled. In a random sample of 22 students,
the mean age is found to be 21.4 years. From past studies, the ages
of enrolled students are normally distributed with a standard
deviation of 10.2 years. Construct a 90% confidence interval for
the mean age of all students currently enrolled.

The admissions officer at a small college compares the scores on
the Scholastic Aptitude Test (SAT) for the school's male and female
applicants. A random sample of 19 male applicants results in a SAT
scoring mean of 1101 with a standard deviation of 30. A random
sample of 9 female applicants results in a SAT scoring mean of 1014
with a standard deviation of 29. Using this data, find the 98%
confidence interval for the true mean difference between the...
