need help with questions 2-7MGMT 650 Fall 2016 Problem Set 11)Using the data file, GRADSURVEY, answer the following:a)What does a row correspond to in the table?b)How many variables are measured on each row?c)For each variable, would you describe it as primarilycategorical, or quantitative? If quantitative, what are theunits? If categorical, is it ordinal or simply nominal?d)Are these data a time series, or are these crosssectional?2. A quality characteristic of interest for a tea-bag-fillingprocess is the weight of the tea in the individual bags. If thebags are under filled, two problems arise. First, customersmay not be able to brew the tea to be as strong as theywish. Second, the company may be in violation of the truthin-labeling laws. In this example, the label weight on thepackage indicates that, on average, there are 5.5 grams oftea in a bag. If the average amount of tea in a bag exceedsthe label weight, the company is giving away product.Getting an exact amount of tea in a bag is problematicbecause of variation in the temperature and humidity insidethe factory, differences in the density of the tea, and theextremely fast filling operation of the machine(approximately 170 bags a minute). The following tableprovides the weight in grams of a sample of 50 bagsproduced in one hour by a single machine:5.85 5.84 5.425.45.53 5.34 5.54 5.45 5.52 5.415.57 5.4 5.535.67 5.4 5.475.77 5.57 5.425.61 5.45 5.445.545.615.585.255.55 5.62 5.66 5.465.53 5.32 5.67 5.295.68 5.5 5.32 5.55.56 5.63 5.5 5.575.645.495.535.675.515.555.585.36a. Compute the arithmetic mean and median.b. Compute the first quartile and third quartile.c. Compute the range, interquartile range, variance,standard deviation, and coefficient of variation.Parts d and e are your chance to show your understanding.You are a consultant brought in by the company and giventhe sample. What are your recommendations to thecompany, based on your reading for this week?d. Interpret the measures of central tendency within thecontext of this problem. Why should the companyproducing the tea bags be concerned about the centraltendency?e. Interpret the measures of variation within the context ofthis problem. Why should the company producing thetea bags be concerned about variation?3.

You ask questions of customers who exit thetheatre. From 470 responses, you find that 45 are youngerthan 6 years old, 83 are 6 to 9 years, 154 are 10 to 14, 18are 15 to 21, and 170 are older than 21.a) Make a frequency table of these categorical data.b) Make a relative frequency table.c) Make a bar chart using counts in the frequency table.d) Would a bar chart of relative frequencies look anydifferent?e) Make a pie chart.f) Write a few sentences summarizing the distributiondemonstrated by your charts and tables.5.In addition to age grouping information, the audiencesinterviewed were also asked if they had seen the moviebefore (Never, Once, More than Once).
