Construct a frequency distribution with 5 classes.
Create a histogram of the data using the frequency table from question 1-a.
A software company asked 100 of its programmers to develop a certain program individually. The following histogram shows the time it takes a programmer to finish the task:
How many classes are there for the given histogram?
What is the class width of the histogram?
What percentage of programmers can complete the task in 30 hours?
How many hours does it take the majority of the programmers to complete the task?
Search the Internet for prices of 11 different laptops.
Compute the mean, median, and mode of these prices.
Find the first and third quartiles of the prices.
In the following image, the memory usage of various processes of a computer running a Windows Operating System is shown:
Create a scatter plot of the memory usage of the processes.
Find the following measures of central tendency of the memory usage in kilobytes (Kb):
Mean
Mode
Median
Find the following measures of dispersion of the memory usage in Kb:
Range
Variance
Standard Deviation
Identify the values that are responsible for the variance of the dataset. Provide a possible solution on how the computer user could decrease the variance of his or her memory usage.
Answer the following questions completely, using proper grammar, complete sentences, and correct terminology:
Explain what it means to have a standard deviation of 0.
Without doing any calculations, is it possible to tell which of the following 2 sets has a higher standard deviation? Explain your answer.
Set 1 = {1,2,3,4,5,6,7,8}
Set 2 = {2,4,6,8,10,12,14,16}

Choose one of the following two prompts to respond to. (Absolutely no plagiarism - all work is ran through a verification site)Option 1:Given this data set – from the NOAA for Manchester, NH, select a random month between January 1930 and December 1957. Begin with this month and analyze the next 25 data values (i.e. 2 years and 1 month) for the variable “TPCP” (See Second Tab in Data Set for variable descriptions). For example, if May 1955 is chosen as the starting month, then the “TPCP” data would be from May 1955 through May 1957. Using Excel, StatCrunch, etc., construct a histogram to represent your sample. Report the sample mean, median, and standard deviation as a part of your discussion of skewness.Determine the interval for the middle 68% of your sample data and relate this to the sample standard deviation.Comment on the similarities and differences between your sample data and that of your classmates. Why are there differences if the samples are drawn from the same population?Option 2:A professor states that in the United States the proportion of college students who own iPhones is .66. She then splits the class into two groups: Group 1 with students whose last name begins with A-K and Group 2 with students whose last name begins with L-Z. She then asks each group to count how many in that group own iPhones and to calculate the group proportion of iPhone ownership. For Group 1 the proportion is p1 and for Group 2 the proportion is p2. To calculate the proportion you take the number of iPhone owners and divide by the total number of students in the group. You will get a number between 0 and 1.What would you expect p1 and p2 to be?Do you expect either of these proportions to be vastly different from the population proportion of .66?Would you be surprised if p1 was different than p2?Would you be surprised if they were the same or similar?What statistical concept describes the relationship between the first letter of someone's last name and whether or not they own an iPhone?
