A researcher who is studying social media habits chose 725 MYbook users at random at the beginning of 2016. Of these users, 67%
said they logged in to MYbook more than twice a day. However, MYbook executives say 52% of users logged in more than twice a day. Which of the following statements is true?A. Sixty-seven percent is a sample and 52% is a population. B. Sixty-seven percent is a statistic and 52% is a parameter. C. Sixty-seven percent and 52% are both statistics. D. Sixty-seven percent is a parameter and 52% is a statistic. E. Sixty-seven percent and 52% are both parameters.
B. Sixty-seven percent is a statistic and 52% is a parameter.
Step-by-step explanation:
Parameters are values that describe a given property for an entire population. Statistics are values that describe a given property for a sample. In this case, the 67% of users pertain to the 725 users sample and, thus is a statistic. The 52% of users pertain to the whole population of users and, therefore, is a parameter.
The answer is B. Sixty-seven percent is a statistic and 52% is a parameter.
By definition the area of a rectangle is: A = l * w Where, l: long w: width So we have to clear the width: w = A / l Substituting the values: w = (234) / (18) = 13 w = 13 feets answer the width, in feet, of the room is 13
