According to the Bureau of Labor​ Statistics, Americans spent on average ​$2,912 in 2016 on entertainment. Assume the population standard deviation of this spending is ​$886. A random sample of 31 adults was selected and was found to have an average spending of ​$2,750 on entertainment. Complete parts a and b.  A) Does this sample provide support for the conclusions of the BLS​ poll?  There is a ( ) chance of observing a sample mean as low as ​$2,750. This probability is  (not low/low) enough​ (0.05) to contradict the findings of the poll. B) Identify the symmetrical interval
