classes.
b) Construct a histogram of the data.
c) Describe the distribution type.

Expert Solution
a) The frequency table based on the given sample is tabulated as:
b) The histogram for the given sample data is plotted using the software as:
c) Based on the given histogram and the frequency table it can be said that the distribution is skewed as most of the data are in the left of the histogram.
d) The ogive is cumulative frequency line chart which is plotted as:
e) The stem and leaf plot of a data set is used to find the distribution of the data and where stem is used as the ones place value of the digit and leaf is made of the tens place value hence the leaf plot is:

A random sample of 13 students were asked how long it took them
to complete a certain exam. The mean length of time was 105.6
minutes, with a standard deviation of 71.7 minutes. Find the lower
bound of the 90% confidence interval for the true mean length of
time it would take for all students to complete the exam.
Round to one decimal place (for example: 108.1)

a. Make a frequency distribution of this data. Use 5 classes
(aka bins) with a class
width of 4, and let the first class have a lower limit of 1....

10) A random sample of 13 students were asked how long it took
them to complete a certain exam. The mean length of time was 120.1
minutes, with a standard deviation of 84.0 minutes. Find the lower
bound of the 90% confidence interval for the true mean length of
time it would take for all students to complete the exam.
Round to one decimal place (for example: 108.1). Write only a
number as your answer. Do not write any units....

A random sample of workers have been surveyed and data collected
on how long it takes them to travel to work. The data are in this
file.
Compute a 99% confidence interval for the expected time taken
to travel to work. Show all your working and state any assumptions
you need to make in order for your confidence interval to be
valid.

You surveyed 20 of your friends and asked them how much they
spend on coffee at Starbucks each week. Their responses ranged from
$0 to $22.50 and the average was $8.64. You decide to create a
histogram of the data. Which of the following is the best set of
bins to use?
a. [0-25.00]
b. [5.00-10.00], [11.00-15.00] and [22.00-25.00]
c. [0-10.00], [5.00-15.00], [10.00-20.00] and [15.00-25.00]
d. [0.00-5.99], [6.00-11.99], [12.00-17.99] and
[18.00-23.99]

Problem 3: A Corporate Perceptions Study surveyed 200 readers
and asked them on how they would rate XYZ Corporation on the
“Quality of Management” and the “Reputation of the Company”. The
two variables of the study were rated on a categorical scale as
excellent, good, and fair. The sample data on 200 responses for the
study is summarized as follows. Conduct an appropriate hypothesis
test for this problem to check if the variables are independent of
each other. Reputation of...

Workers in several industries were surveyed to determine the
proportion of workers who feel their industry is understaffed. In
the government sector, 37% of the respondents said they were
understaffed, in the health care sector 33% said they were
understaffed and in the education sector 28% said they were
understaffed (USA Today, January 11, 2010). Suppose that 200
workers were surveyed in each industry.
b) Assuming the same sample size will be used in each industry,
how large would the...
