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.
So the way to answer this question is to convert minute to seconds We know that a minute has 60 seconds The problem states that the hummingbird flaps its wings 80 times per second So 80 times per second x 60 seconds = 4800 times would be the final answer.
