What is the population? 

A) New remote control buttons

B) the selected 36 buttons

C) electronic firms

What is the variable of interest?  and is this variable Quantitative or Qualitative? 

A) lifetime before becoming intermittent, qualitative

B) Success = lasts longer than 1200, quantitative 

C) lifetime before becoming intermittent, quantitative

D) Success = lasts longer than 1200, qualitative

 

A consumer electronics firm has developed a new type of remote control button that is designed to operate longer before becoming intermittent. The best button on the market lasts an average of 1200 hours. A random sample of 36 new buttons is selected and each is tested in continuous operation until becoming intermittent. The resulting lifetime of each button was recorded and found to have a sample mean of 1275 hours. What is the population? [ Select ] What is the variable of interest? and is this variable Quantitative or Qualitative? [ Select ] In other words: what is the one piece of info we care about for each individual in the population? Is it a quantitative measurement? Or do we determine if each individual belongs to a certain category (referred to as success) or not (failure)? >
