Sam Suffolk is a student in MAT103 at SCCC. Sam has data from a random sample of 20 students that represents how many miles (rounded to the nearest whole mile) each student lives from the SCCC Ammerman campus. Sam organizes this data in the following frequency distribution table. Look at the table carefully and answer the questions that follow.

Sam made two mistakes when creating the classes for this table. Assuming Sam's frequencies are correct, despite the errors in the class limits, answer each of the following.
Note: The first two lower class limits are correct.
(a) Identify Sam's mistakes.
(b) Can we determine how many students live 10 miles from the campus? If so, how many? If not, why not?
(c) Give an estimate of the number of students in the sample that live more than 25 miles from the campus. If more than one frequency is possible, state all possible values.

A random sample of 30 Suffolk University employees had an
average commute length of 13.5 miles, with a standard deviation of
7.5 miles. What is the 90% confidence interval for the mean commute
length of all Suffolk employees? Use 4 non-zero decimal places in
your calculations.

A student is interested in the sleep quality of students. That
student selects a random sample of 21 students (age 19-24 years)
from each four undergraduate years (Freshman, Sophomore, Junior and
Senior), and applies Pittsburgh Sleep Quality Index (PSQI) and
obtains their responses. PSQI includes 19 self-reported items and
is designed to evaluate overall sleep quality (Data are presented
in Table 1 below). The student is interested in determining whether
there is any evidence of a difference in sleep quality...

A student conducts a simple random sample of students from her
high school and finds that 21 out of 100 students in her sample
regularly walk to school. Give a point estimate for the proportion
of all students at her high school who regularly walk to school.
For each combination of sample size and sample proportion, find the
approximate margin of error for the 95% confidence level. (Round
