Question
Refer to the following contingency breakdown of responses to a survey of "How confident are you that you have saved enough to retire?" What is the relative frequency of females below who indicated that they were "Somewhat Confident"? 20 23 45 63 Tesla Motors used focus groups in order to help design their now Model X and found: Customer Satisfaction surveys are a better way to gauge customer preferences. Women wanted safety, a third row of seats and the ability to get kids in and out easily. Men wanted speed, high-tech computer systems, and a great looking car. Primary research in the form of focus groups did not work well. A data set consists of 28 numbers and has a minimum value of 28 and a maximum value of 490. Determine the class boundaries if the data values are discrete. Select the correct choice below: 0 to 100, 101 to 200, 201 to 300, 301 to 400, 401 to 500 0 to 93, 94 to 187, 188 to 281, 282 to 375, 376 to 468, 469 to 562 0 to less than 100, 100 to less than 200, 200 to less than 300, 300 to less than 400, 400 to less than 500 0 to less than 93, 93 to less than 187, 187 to less than 281, 281 to less than 375, 375 to less than 468, 468 to less than 562 A data set consists of 28 numbers and has a minimum value of 28 and a maximum value of 490.

Ans:
13)Total count=63+135+99+3=300
Relative frquecy of females who indicated that they were somewhat confident=60/300=1/5=0.2
Option A is correct.
14)Option B is correct.
Women anted safety,a third row of seats and ability to get kids in and out easily.
17) Option B is correct.
A frequency polygon is essentially a line graph,whose advatage is being able to compare two or more frequency distributions.
